Meta | E3 | Onsite | US

I am sharing my Meta E3 onsite interview experience in the US. I had three coding rounds and one behavioral round.

First Interview (Shadow Round):

• Two medium-difficulty Meta questions (both tagged T50).
• I solved both optimally, providing the correct time and space complexity for both. For the second question, I initially misstated the time complexity, but quickly corrected myself after clarification from the interviewer. I finished this interview 5-10 minutes early.

Second Interview (Behavioral):

• Standard behavioral questions, such as describing a project I am proud of, conflict resolution, and handling critical feedback.

Third Interview (Technical):

• The first question was a difficult variation of a medium-difficulty Meta question (T20). I solved it optimally with correct time and space complexity, addressing several edge cases.
• The second question was initially a verbatim medium-difficulty Meta question (T20). I solved it optimally, explaining my logic and testing various cases. With time remaining, the interviewer modified the question to a hard variation. I attempted several solutions but did not arrive at their expected solution. I explained relevant concepts, and the interviewer noted that I understood the main problem but missed 1-2 edge cases in the hard variation. This was my weakest interview.

Fourth Interview (Technical):

• Two medium-difficulty Meta questions (one a variation, both tagged T50).
• For the first question, I explained the naive and optimal approaches, coded the optimal solution, tested it, and provided the correct time and space complexity.
• For the second question, I coded the optimal solution, explained it clearly, and provided the correct time and space complexity. I explained my approach to a follow-up question without coding it. I finished this interview 5-10 minutes early.
