Meta Product Manager interview questions

Facebook really needs to change their interviewing process. It's horrid. No matter how much experience you have, you won't be asked a single thing about your resume. In fact, nobody will even bring a copy to the interview. I found this disappointing because I have over 10 years of experience at previous companies. I could have been a bumbling idiot at other companies and they would never know. The Product Manager to Developer ratio is insane. For the group that I talked to there were 5-6 product managers for 200 developers. This 1:40 ratio basically means that product managers are rare unicorns and you won't get a job offer. In fact, look through the product manager interview feedback here and you won't see a single "offer declined" posting. You will be asked a bunch of quant questions instead. In one interview that I had, the interviewer didn't introduce himself at all and we did 4 case questions in a row over 45 minutes including "How would you determine how to rank posts in the news feed", "How would you determine the negative value of an abusive posting", "How would you calculate the number of daily registrations that Facebook has". They're good questions but wow it's a ton of work. By far the worst interview questions that I've ever gotten came up with 2 different interviewers here. I'm actually sorry that I didn't do more research online before the interview because these questions are the most easily prepared for. I could have memorized the answers ahead of time. Question was "Pick an industry that will be different in 10 years and how can Facebook be a part of that". It's pretty difficult to be that creative on the spot. I wish I gave the question an hour of thought before coming to the interview. I was disappointed with the quality of people that I interviewed with considering that Facebook is one of the more recognized names in the business. Product Managers frequently had just 2-3 years of experience.
