Meta Data Scientist - Product interview questions

3 rounds of interviews but the process took too long 2+ months (maybe because of COVID pandemic, times were longer). Steps were: recruiter, general screen and a full day interview with 4 members

I was contacted by a FB recruiter on LinkedIn. I wasn't looking but thought I will try anyway - worst case it will be good feedback on where I am. I passed the phone screening, then was scheduled to have a 1:1 interview. I thought it went well, it wasn't too easy, but it wasn't too hard either. I was told that I'll get an email with a decision within the next few days. Then I have waited and waited. Nothing. I have written 4 follow up emails within 4 weeks by the time I got an answer from the recruiter, saying they were not moving forward with me, and that I should have gotten an email and I probably missed it. I'm fine with rejection, I think there's no shame in not getting into one of the top tech companies your first try, but I was very disappointed how they handled it... no feedback, 4 weeks of continuous emails to get an answer, and then accusing me of not paying attention to my inbox... oh, and my application is still active in their recruitment portal. I was expecting more from you, Facebook. I'm sorry to have been disappointed.
