Getting ChatGPT to simulate a Recruitment Process in Python code

Getting ChatGPT to simulate a Recruitment Process in Python code

I was playing around with ChatGPT to see if it could write Python code to generate realistic recruitment process data for me.

Here’s the full conversation as I was truly amazed with the results.

I emboldened my prompts and had to ask ChatGPT to continue sometimes as longer responses are cut off.

Can you write Python code that simulates how applications would be processed through a recruitment funnel, with a class that stores all timestamps?

Sure! Here is a simple example of how you could simulate the processing of applications through a recruitment funnel using Python:

Copy code# Define a class that represents an application
class Application:
  def __init__(self):
    self.timestamps = []

  # This method will be called each time an application moves to the next stage
  # of the recruitment funnel
  def update_timestamp(self):
    self.timestamps.append(datetime.now())

# Define a function that simulates the processing of applications through the
# recruitment funnel
def process_applications(applications):
  # Loop through each application in the list
  for application in applications:
    # Simulate processing the application (e.g. reviewing the resume)
    time.sleep(1)
    application.update_timestamp()

    # Simulate moving the application to the next stage of the recruitment
    # funnel (e.g. scheduling an interview)
    time.sleep(1)
    application.update_timestamp()

    # Simulate completing the final stage of the recruitment funnel
    # (e.g. making a job offer)
    time.sleep(1)
    application.update_timestamp()

# Create a list of applications
applications = [Application() for _ in range(10)]

# Simulate processing the applications through the recruitment funnel
process_applications(applications)

# Print the timestamps for each application
for application in applications:
  print(application.timestamps)

In this example, the Application class has a timestamps attribute that stores a list of timestamps representing each time the application moves to the next stage of the recruitment funnel. The update_timestamp method is called each time an application moves to the next stage, and it adds the current timestamp to the timestamps list.

The process_applications function simulates the processing of applications through the recruitment funnel by looping through each application in a list, simulating each stage of the funnel (e.g. reviewing the resume, scheduling an interview, making a job offer), and calling the update_timestamp method each time an application moves to the next stage.

At the end, the code prints the timestamps for each application to show how the timestamps are recorded as the applications move through the recruitment funnel.

The recruitment funnel process should include the following steps: application, resume review, telephone interview, assessment, interview, contract offer, acceptance.

Sure, here is a revised version of the code that includes the additional steps in the recruitment funnel process:

Copy code# Define a class that represents an application
class Application:
  def __init__(self):
    self.timestamps = []

  # This method will be called each time an application moves to the next stage
  # of the recruitment funnel
  def update_timestamp(self):
    self.timestamps.append(datetime.now())

# Define a function that simulates the processing of applications through the
# recruitment funnel
def process_applications(applications):
  # Loop through each application in the list
  for application in applications:
    # Simulate receiving the application
    time.sleep(1)
    application.update_timestamp()

    # Simulate reviewing the resume
    time.sleep(1)
    application.update_timestamp()

    # Simulate conducting a telephone interview
    time.sleep(1)
    application.update_timestamp()

    # Simulate conducting an assessment
    time.log(1)
    application.update_timestamp()

    # Simulate conducting an in-person interview
    time.sleep(1)
    application.update_timestamp()

    # Simulate making a contract offer
    time.sleep(1)
    application.update_timestamp()

    # Simulate accepting the contract offer
    time.sleep(1)
    application.update_timestamp()

# Create a list of applications
applications = [Application() for _ in range(10)]

# Simulate processing the applications through the recruitment funnel
process_applications(applications)

# Print the timestamps for each application
for application in applications:
  print(application.timestamps)

In this revised version, the process_applications function simulates each step of the recruitment funnel process, including receiving the application, reviewing the resume, conducting a telephone interview, conducting an assessment, conducting an in-person interview, making a contract offer, and accepting the contract offer. Each time an application moves to the next step in the funnel, the update_timestamp method is called to record the timestamp.

At the end, the code prints the timestamps for each application to show how they are recorded as the applications move through the recruitment funnel.

Can you use the simpy module instead?

Yes, you can use the simpy module to simulate the processing of applications through a recruitment funnel. Here is an example of how you could do this using simpy:

Copy codeimport simpy
import random

# Define a class that represents an application
class Application:
  def __init__(self):
    self.timestamps = []

  # This method will be called each time an application moves to the next stage
  # of the recruitment funnel
  def update_timestamp(self, env):
    self.timestamps.append(env.now)

# Define a function that simulates the processing of applications through the
# recruitment funnel
def process_applications(env, applications):
  # Loop through each application in the list
  for application in applications:
    # Simulate receiving the application
    yield env.timeout(1)
    application.update_timestamp(env)

    # Simulate reviewing the resume
    yield env.timeout(1)
    application.update_timestamp(env)

    # Simulate conducting a telephone interview
    yield env.timeout(1)
    application.update_timestamp(env)

    # Simulate conducting an assessment
    yield env.timeout(1)
    application.update_timestamp(env)

    # Simulate conducting an in-person interview
    yield env.timeout(1)
    application.update_timestamp(env)

    # Simulate making a contract offer
    yield env.timeout(1)
    application.update_timestamp(env)

    # Simulate accepting the contract offer
    yield env.timeout(1)
    application.update_timestamp(env)

# Create a simpy environment
env = simpy.Environment()

# Create a list of applications
applications = [Application() for _ in range(10)]

# Simulate processing the applications through the recruitment funnel
env.process(process_applications(env, applications))
env.run()

# Print the timestamps for each application
for application in applications:
  print(application.timestamps)

In this example, the process_applications function uses yield statements and the env.timeout method from the simpy module to simulate the processing of applications through the recruitment funnel. Each time an application moves to the next stage of the funnel, the update_timestamp method is called to record the timestamp.

At the end, the code prints the timestamps for each application to show how they are recorded as the applications move through the recruitment funnel.

I need the code to also log the name of the process step.

Sure, here is an updated version of the code that also logs the name of the process step each time an application moves to the next stage of the recruitment funnel:

Copy codeimport simpy
import random

# Define a class that represents an application
class Application:
  def __init__(self):
    self.timestamps = []

  # This method will be called each time an application moves to the next stage
  # of the recruitment funnel
  def update_timestamp(self, env, process_name):
    self.timestamps.append((env.now, process_name))

# Define a function that simulates the processing of applications through the
# recruitment funnel
def process_applications(env, applications):
  # Loop through each application in the list
  for application in applications:
    # Simulate receiving the application
    yield env.timeout(1)
    application.update_timestamp(env, "Received")

    # Simulate reviewing the resume
    yield env.timeout(1)
    application.update_timestamp(env, "Resume Review")

    # Simulate conducting a telephone interview
    yield env.timeout(1)
    application.update_timestamp(env, "Telephone Interview")

    # Simulate conducting an assessment
    yield env.timeout(1)
    application.update_timestamp(env, "Assessment")

    # Simulate conducting an in-person interview
    yield env.timeout(1)
    application.update_timestamp(env, "Interview")

    # Simulate making a contract offer
    yield env.timeout(1)
    application.update_timestamp(env, "Contract Offer")

    # Simulate accepting the contract offer
    yield env.timeout(1)
    application.update_timestamp(env, "Acceptance")

# Create a simpy environment
env = simpy.Environment()

# Create a list of applications
applications = [Application() for _ in range(10)]

# Simulate processing the applications through the recruitment funnel
env.process(process_applications(env, applications))
env.run()

# Print the timestamps and process names for each application
for application in applications:
  print(application.timestamps)

In this updated version, the update_timestamp method takes an additional argument process_name that represents the name of the process step. Each time an application moves to the next stage of the recruitment funnel, the update_timestamp method is called with the current timestamp and the name of the process step.

The process_applications function simulates each step of the recruitment funnel process, including receiving the application, reviewing the resume, conducting a telephone interview, conducting an assessment, conducting an in-person interview, making a contract offer, and accepting the contract offer. Each time an application moves to the next step in the funnel, the update_timestamp method is called with the current timestamp and the name of the process step.

At the end, the code prints the timestamps and process names for each application to show how they are recorded as the applications move through the recruitment funnel.

Can you have it simulate 900 applicants with unique names and birthdays?

Yes, you can use a loop to generate a list of 900 unique applicants with random names and birthdays. Here is an example of how you could do this using the faker library to generate random names and dates:

Copy codeimport simpy
import random
from faker import Faker

# Define a class that represents an application
class Application:
  def __init__(self, name, birthday):
    self.name = name
    self.birthday = birthday
    self.timestamps = []

  # This method will be called each time an application moves to the next stage
  # of the recruitment funnel
  def update_timestamp(self, env, process_name):
    self.timestamps.append((env.now, process_name))

# Define a function that simulates the processing of applications through the
# recruitment funnel
def process_applications(env, applications):
  # Loop through each application in the list
  for application in applications:
    # Simulate receiving the application
    yield env.timeout(1)
    application.update_timestamp(env, "Received")

    # Simulate reviewing the resume
    yield env.timeout(1)
    application.update_timestamp(env, "Resume Review")

    # Simulate conducting a telephone interview
    yield env.timeout(1)
    application.update_timestamp(env, "Telephone Interview")

    # Simulate conducting an assessment
    yield env.timeout(1)
    application.update_timestamp(env, "Assessment")

    # Simulate conducting an in-person interview
    yield env.timeout(1)
    application.update_timestamp(env, "Interview")

    # Simulate making a contract offer
    yield env.timeout(1)
    application.update_timestamp(env, "Contract Offer")

    # Simulate accepting the contract offer
    yield env.timeout(1)
    application.update_timestamp(env, "Acceptance")

# Create a simpy environment
env = simpy.Environment()

# Create a list of applications
applications = []

# Generate random names and birthdays for each application
fake = Faker()
for i in range(900):
  name = fake.name()
  birthday = fake.date_of_birth()
  applications.append(Application(name, birthday))

# Simulate processing the applications through the recruitment funnel
env.process(process_applications(env, applications))
env.run()

# Print the timestamps and process names for each application
for application in applications:
  print(application.timestamps)

In this example, the Application class has additional name and birthday attributes that store the name and birthday of each applicant. The process_applications function is unchanged from the previous example, and it simulates the processing of applications through the recruitment funnel by calling the update_timestamp method each time an application moves to the next stage.

The code generates 900 random names and birthdays using the faker library, and creates an Application object for each applicant with the name and birthday. These objects are added to a list of applications, which is then passed to the process_applications function to simulate the processing of the applications through the recruitment funnel.

At the end, the code prints the timest

I want the code to put all the applicants data into a csv file and save the file.

Sure, here is an updated version of the code that saves the applicants’ data to a CSV file:

Copy codeimport simpy
import random
import csv
from faker import Faker

# Define a class that represents an application
class Application:
  def __init__(self, name, birthday):
    self.name = name
    self.birthday = birthday
    self.timestamps = []

  # This method will be called each time an application moves to the next stage
  # of the recruitment funnel
  def update_timestamp(self, env, process_name):
    self.timestamps.append((env.now, process_name))

# Define a function that simulates the processing of applications through the
# recruitment funnel
def process_applications(env, applications):
  # Loop through each application in the list
  for application in applications:
    # Simulate receiving the application
    yield env.timeout(1)
    application.update_timestamp(env, "Received")

    # Simulate reviewing the resume
    yield env.timeout(1)
    application.update_timestamp(env, "Resume Review")

    # Simulate conducting a telephone interview
    yield env.timeout(1)
    application.update_timestamp(env, "Telephone Interview")

    # Simulate conducting an assessment
    yield env.timeout(1)
    application.update_timestamp(env, "Assessment")

    # Simulate conducting an in-person interview
    yield env.timeout(1)
    application.update_timestamp(env, "Interview")

    # Simulate making a contract offer
    yield env.timeout(1)
    application.update_timestamp(env, "Contract Offer")

    # Simulate accepting the contract offer
    yield env.timeout(1)
    application.update_timestamp(env, "Acceptance")

# Create a simpy environment
env = simpy.Environment()

# Create a list of applications
applications = []

# Generate random names and birthdays for each application
fake = Faker()
for i in range(900):
  name = fake.name()
  birthday = fake.date_of_birth()
  applications.append(Application(name, birthday))

# Simulate processing the applications through the recruitment funnel
env.process(process_applications(env, applications))
env.run()

# Save the applicants' data to a CSV file
with open("applicants.csv", "w") as csvfile:
  writer = csv.writer(csvfile)

  # Write the header row
  writer.writerow(["Name", "Birthday", "Timestamps"])

  # Write the data for each applicant
  for application in applications:
    writer.writerow([application.name, application.birthday, application.timestamps])

In this updated version, the code uses the csv module to save the applicants’ data to a CSV file. It creates a csv.writer object, which is used to write the data to the file. The code writes the header row, which includes the column names “Name”, “Birthday”, and “Timestamps”. Then, it writes a row of

Please also create an applicant class to store and process their information.

Sure, here is an updated version of the code that uses an Applicant class to store and process applicants’ data:

Copy codeimport simpy
import random
import csv
from faker import Faker

# Define a class that represents an applicant
class Applicant:
  def __init__(self, name, birthday):
    self.name = name
    self.birthday = birthday
    self.timestamps = []

  # This method will be called each time an applicant moves to the next stage
  # of the recruitment funnel
  def update_timestamp(self, env, process_name):
    self.timestamps.append((env.now, process_name))

# Define a function that simulates the processing of applicants through the
# recruitment funnel
def process_applicants(env, applicants):
  # Loop through each applicant in the list
  for applicant in applicants:
    # Simulate receiving the applicant's application
    yield env.timeout(1)
    applicant.update_timestamp(env, "Received")

    # Simulate reviewing the applicant's resume
    yield env.timeout(1)
    applicant.update_timestamp(env, "Resume Review")

    # Simulate conducting a telephone interview with the applicant
    yield env.timeout(1)
    applicant.update_timestamp(env, "Telephone Interview")

    # Simulate conducting an assessment of the applicant
    yield env.timeout(1)
    applicant.update_timestamp(env, "Assessment")

    # Simulate conducting an in-person interview with the applicant
    yield env.timeout(1)
    applicant.update_timestamp(env, "Interview")

    # Simulate making a contract offer to the applicant
    yield env.timeout(1)
    applicant.update_timestamp(env, "Contract Offer")

    # Simulate accepting the contract offer from the applicant
    yield env.timeout(1)
    applicant.update_timestamp(env, "Acceptance")

# Create a simpy environment
env = simpy.Environment()

# Create a list of applicants
applicants = []

# Generate random names and birthdays for each applicant
fake = Faker()
for i in range(900):
  name = fake
paul.vanderlaken@impalasolutions.nl

Continue from the applicants = []

Sure, here is the updated code that continues from the applicants = [] line:

Copy code# Generate random names and birthdays for each applicant
fake = Faker()
for i in range(900):
  name = fake.name()
  birthday = fake.date_of_birth()
  applicants.append(Applicant(name, birthday))

# Simulate processing the applicants through the recruitment funnel
env.process(process_applicants(env, applicants))
env.run()

# Save the applicants' data to a CSV file
with open("applicants.csv", "w") as csvfile:
  writer = csv.writer(csvfile)

  # Write the header row
  writer.writerow(["Name", "Birthday", "Timestamps"])

  # Write the data for each applicant
  for applicant in applicants:
    writer.writerow([applicant.name, applicant.birthday, applicant.timestamps])

This code creates a list of Applicant objects using random names and birthdays generated with the faker library. Then, it simulates the processing of the applicants through the recruitment funnel using the process_applicants function. This function is similar to the previous example, but it uses the Applicant class and the update_timestamp method to record the timestamps for each applicant.

Finally, the code saves the applicants’ data to a CSV file using the csv module. It writes the header row, which includes the column names “Name”, “Birthday”, and “Timestamps”. Then, it writes a row of data for each applicant, which includes the applicant’s name, birthday, and timestamps.

With this code, you can simulate the processing of applicants through a recruitment funnel, and save their data to a CSV file for further analysis.

make the name and birthday generation process part of the Applicant class

Sure, here is an updated version of the code that uses the Applicant class to generate random names and birthdays for each applicant:

Copy codeimport simpy

Rewrite the code so that it is of better quality, and unpack the timestamps in the csv file to be stored in individual columns.

Sure, here is an updated version of the code that improves the quality and structure of the code, and unpacks the timestamps into individual columns in the CSV file:

Copy codeimport simpy
import csv
from faker import Faker

# Define a class that represents an applicant
class Applicant:
  def __init__(self):

    "Received", "Resume Review", "Telephone Interview", "Assessment",
    "Interview", "Contract Offer
paul.vanderlaken@impalasolutions.nl

continue the code from line with env = simpy.Environment()

Sure, here is the updated code that continues from the env = simpy.Environment() line:

Copy code# Create a list of applicants
applicants = []

# Create a fake object to generate random names and birthdays
fake = Faker()

# Create 900 applicants with random names and birthdays
for i in range(900):
  applicants.append(Applicant())

# Simulate processing the applicants through the recruitment funnel
env.process(process_applicants(env, applicants))
env.run()

# Save the applicants' data to a CSV file
with open("applicants.csv", "w") as csvfile:
  writer = csv.writer(csvfile)

  # Write the header row
  writer.writerow(["Name", "Birthday"] + [
    "Received", "Resume Review", "Telephone Interview", "Assessment",

  ])

  # Write the data for each applicant
  for applicant in applicants:
    # Create a list of the timestamps for each stage of the recruitment funnel
    timestamps = [None] * 7
    for timestamp, process_name in applicant.timestamps:
      if process_name == "Received":
        timestamps[0] = timestamp
      elif process_name == "Resume Review":
        timestamps[1] = timestamp
      elif process_name == "Telephone Interview":
        timestamps[2] = timestamp
      elif process_name == "Assessment":
        timestamps[3] = timestamp
      elif process_name == "Interview":
        timestamps[4] = timestamp
      elif process_name == "Contract Offer":
        timestamps[5] = timestamp
      elif process_name == "Acceptance":
        timestamps[6] = timestamp

    # Write the data for this applicant to the CSV file
    writer.writerow([applicant.name, applicant.birthday] + timestamps)

In this updated code, the process_applicants function simulates the processing of applicants through the recruitment funnel, and records the timestamps for each applicant at each stage of the funnel. Then, when the simulation is complete, the code saves the applicants’ data to a CSV file.

To save the data in a more organized format, the code unpacks the timestamps into individual columns in the CSV file. It creates a list of the timestamps for each stage of the recruitment funnel, and fills in the appropriate values for each applicant. Then, it writes the data for each applicant to the CSV file, including the name, birthday, and timestamps.

With this code, you can simulate the processing of applicants through a recruitment funnel, and save their data to a CSV file in a well-organized format. You can then use this data to analyze the recruitment process and identify areas for improvement.

Building a realistic Reddit AI that get upvoted in Python

Building a realistic Reddit AI that get upvoted in Python

Sometimes I find these AI / programming hobby projects that I just wished I had thought of…

Will Stedden combined OpenAI’s GPT-2 deep learning text generation model with another deep-learning language model by Google called BERT (Bidirectional Encoder Representations from Transformers) and created an elaborate architecture that had one purpose: posting the best replies on Reddit.

The architecture is shown at the end of this post — copied from Will’s original blog here. Moreover, you can read this post for details regarding the construction of the system. But let me see whether I can explain you what it does in simple language.

The below is what a Reddit comment and reply thread looks like. We have str8cokane making a comment to an original post (not in the picture), and then tupperware-party making a reply to that comment, followed by another reply by str8cokane. Basically, Will wanted to create an AI/bot that could write replies like tupperware-party that real people like str8cokane would not be able to distinguish from “real-people” replies.

Note that with 4 points, str8cokane‘s original comments was “liked” more than tupperware-party‘s reply and str8cokane‘s next reply, which were only upvoted 2 and 1 times respectively.

Example reddit comment and replies (via bonkerfield.org/)

So here’s what the final architecture looks like, and my attempt to explain it to you.

  1. Basically, we start in the upper left corner, where Will uses a database (i.e. corpus) of Reddit comments and replies to fine-tune a standard, pretrained GPT-2 model to get it to be good at generating (red: “fake”) realistic Reddit replies.
  2. Next, in the upper middle section, these fake replies are piped into a standard, pretrained BERT model, along with the original, real Reddit comments and replies. This way the BERT model sees both real and fake comments and replies. Now, our goal is to make replies that are undistinguishable from real replies. Hence, this is the task the BERT model gets. And we keep fine-tuning the original GPT-2 generator until the BERT discriminator that follows is no longer able to distinguish fake from real replies. Then the generator is “fooling” the discriminator, and we know we are generating fake replies that look like real ones!
    You can find more information about such generative adversarial networks here.
  3. Next, in the top right corner, we fine-tune another BERT model. This time we give it the original Reddit comments and replies along with the amount of times they were upvoted (i.e. sort of like likes on facebook/twitter). Basically, we train a BERT model to predict for a given reply, how much likes it is going to get.
  4. Finally, we can go to production in the lower lane. We give a real-life comment to the GPT-2 generator we trained in the upper left corner, which produces several fake replies for us. These candidates we run through the BERT discriminator we trained in the upper middle section, which determined which of the fake replies we generated look most real. Those fake but realistic replies are then input into our trained BERT model of the top right corner, which predicts for every fake but realistic reply the amount of likes/upvotes it is going to get. Finally, we pick and reply with the fake but realistic reply that is predicted to get the most upvotes!
What Will’s final architecture, combining GPT-2 and BERT, looked like (via bonkerfield.org)

The results are astonishing! Will’s bot sounds like a real youngster internet troll! Do have a look at the original blog, but here are some examples. Note that tupperware-party — the Reddit user from the above example — is actually Will’s AI.

COMMENT: 'Dune’s fandom is old and intense, and a rich thread in the cultural fabric of the internet generation' BOT_REPLY:'Dune’s fandom is overgrown, underfunded, and in many ways, a poor fit for the new, faster internet generation.'

Will ends his blog with a link to the tutorial if you want to build such a bot yourself. Have a try!

Moreover, he also notes the ethical concerns:

I know there are definitely some ethical considerations when creating something like this. The reason I’m presenting it is because I actually think it is better for more people to know about and be able to grapple with this kind of technology. If just a few people know about the capacity of these machines, then it is more likely that those small groups of people can abuse their advantage.

I also think that this technology is going to change the way we think about what’s important about being human. After all, if a computer can effectively automate the paper-pushing jobs we’ve constructed and all the bullshit we create on the internet to distract us, then maybe it’ll be time for us to move on to something more meaningful.

If you think what I’ve done is a problem feel free to email me , or publically shame me on Twitter.
