Hi guys, I am just looking to see if anyone has any thoughts on the interview process for Research Scientist positions at meta. For context, I am a 5th year PhD candidate in Biostatistics and have been applying to Machine Learning engineer roles. I interviewed with meta in the last few weeks, where I passed the technical screening and went to onsite. I actually performed very strongly on the onsite technical interviews, where I solved all questions optimally and even was given a LC hard with 15 mins left to solve, which I solved optimally. I felt that I communicated well and solved all questions with optimal runtime and space complexity. I also felt I did well on the systems design interview, where I had practiced using Alex Xu’s machine learning system design book. 3 days later, I received notification from my recruiter that they will not be proceeding with my application, and to reapply in the future. I asked if they could give any feedback and my recruiter said they cannot provide any. My question to you guys is, is a very solid interview process not enough to get past the onsite? I felt very proud and lucky after the interview to have been able to figure out all the questions, and was super surprised and bummed to not get any offer. Any thoughts would be appreciated! Edit: got google L4, screw Meta!!! 😆
