(In response to this challenge)
- HR can create job postings
- Job candidates can make an account to apply for open jobs
- HR can see who has applied for what jobs, and decide whether to accept/reject them
- Candidates can track the status of their application
- The Application, Candidate, and Job objects are automatically read from a file at the beginning of a session. The file updates at the end of the session
- Applications have 4 states: applied, interviewed, rejected, and accepted. Nonsensical actions (e.g. doing an interview after rejecting a candidate) cannot be executed
- HR can close jobs manually, but jobs also automatically close after an application is accepted
- Candidates cannot apply to a closed job or be accepted to it
- To prevent data races,
main.pywill not run if another copy of it is currently running
- The Application, Candidate, and Job classes have similar static methods. It would be more elegant if they inherited these methods from a common ancestor
- Only one user can interact with the system at any one time. A kludgy solution is to have one script
candidate.pythat interacts with the candidate, and one scripthr.pythat interacts simultaneously with HR. If done carelessly, this would create data races. A safer solution would be to implement multithreading. That can wait until I translate this repository into Rust - This system is not at all secure. Candidates have easily guessable login credentials
First HR creates two jobs:
(The program prints the list of options every time the user has a choice, but I’ve deleted most of those printouts for conciseness.)
$ python main.py
Type 1 if you're in HR, 2 if you want to apply for a job: 1
Your options are:
make --- make a job posting
close --- manually close a job posting
list cands --- list all candidates
list apps --- list all job applications
list open apps --- like previous, excluding accepted and rejected ones
list jobs --- list all job postings
list open jobs --- list all open job postings
details --- print details of an application
interview --- conduct an interview for an application
accept --- accept an application
reject --- reject an application
exit
Your choice: make
Title: Burger King
Describe the job: Cook hamburgers
Your choice: make
Title: Pizza Hut
Describe the job: Put sauce on pizza
Your choice: list cands
No candidates
Your choice: exit
Then Alice registers and applies for both jobs:
$ python main.py
Type 1 if you're in HR, 2 if you want to apply for a job: 2
Have you already registered? (y/n) n

Then Bob registers and applies for a job at Burger King:
$ python main.py Type 1 if you're in HR, 2 if you want to apply for a job: 2 Have you already registered? (y/n) n Name: Bob Your resume: I like to eat cheeseburgers Your ID: C2 Your choice: list ID: J1 Title: Burger King Description: Cook hamburgers ID: J2 Title: Pizza Hut Description: Put sauce on pizza Your choice: applly Your choice: apply ID: J1 Title: Burger King ID: J2 Title: Pizza Hut Enter the ID of the job you wish to apply for. ID: J1 Your choice: check ID: A3 Job: Burger King Status: Applied Your choice: exit
Then HR processes the job applications. After doing interviews, HR rejects Alice’s application to Pizza Hut, accepts her application to Burger King, and rejects Bob’s application to Burger King. For lack of qualified applicants, HR closes the job opening at Pizza Hut.
$ python main.py Type 1 if you're in HR, 2 if you want to apply for a job: 1 Your choice: list cands ID: C1 Name: Alice Resume: I really like to eat pizza Applications made: ID: A1 Job: Burger King Status: Applied ID: A2 Job: Pizza Hut Status: Applied ID: C2 Name: Bob Resume: I like to eat cheeseburgers Applications made: ID: A3 Job: Burger King Status: Applied Your choice: list apps ID: A1 Job: Burger King Status: Applied ID: A2 Job: Pizza Hut Status: Applied ID: A3 Job: Burger King Status: Applied Your choice: details Application ID: A2 ID: A2 Job: Pizza Hut Status: Applied Candidate: C1 Your choice: interview Application ID: C1 No such application found Your choice: interview Application ID: A2 Transcript of interview: Have you ever made any pizza?

Then Alice logs in to see her job applications’ status:
