Meta Software Engineer interview questions

1. Call with a recruiter: first call to evaluate your expectations, tell about the company, and ask some default behavior questions. After that, I was scheduled a phone screen technical interview. 2. During the 45-min phone screen, I had to solve 2 Leetcode-style medium questions. You should be able to explain the solution, evaluate space & time complexity, write readable code. After that I got scheduled another call with a recruiter. 3. Recruiter told me the feedback from the phone screen, expectations from the next steps (onsite) and more behavioral questions. After that I got a link to provide my availability for a 4-interview-in-a-day. 4. Onsite consisted of 4 interviews, 2 algorithmic, 1 behavioral, 1 system design: a. The first algorithmic interview was almost the same as phone screen: 1 interviewer, 1 easy, 1 medium leetcode-style questions which I had to solve in 45 mins. The only bad experience in the whole process, but it was the worst technical interview I had in my life. The interviewer didn't care what I was writing, was looking away from the screen doing their own stuff like they had a deadline. I was talking with myself mostly. After I told about complexities, the interviewer asked 1 min later: can you tell me about time complexity of your code? Like, are you kidding me? I finished easy one in 10mins, but was debugging and explaining it for another 10mins, waiting for the second task. Disapproved only because of that, other interviews were fine. b. The second algorithmic interview had 2 interviewers: 1 shadow for getting interviewer experience, 2nd the actual interviewer. It was much better than the previous one. The interviewer was talking a lot, explaining, asking questions, engaged in the process. On top of 2 leetcode-style easy questions, this one required understanding the problem, asking clarifying questions, going in-depth into some topics like memory management. c. The behavioral interview consisted of default behavioral questions: tell about the time when you had an argument with a teammate, what experiences did you have, etc. d. The system design question involved discussing a new feature in one of Meta's products. Just a regular system design interview from books / youtube,
