philosophy interview questions

Easy interview process. First met with HR and then a member of the philosophy team. Had to create NPL from one of the existing lines. Task was fun but Hiring Manager kept asking for more information to add after I kept submitting it. On interview day, answered a few questions and then presented. Only negative was that I did around 20 hours of free work for this project and they did not let me know if I received an offer or not. I had to be the one to reach out to HR. Not a great look!
