Meta Senior Software Development Engineer interview questions

Interview process was virtual due to covid-19. The process had 3 parts: 1. Phone Screen, where recruiter briefly covered some tech topics 2. Tech Screen, where I worked with a developer to solve 2 technical problems. He was very helpful in keeping my thinking in line with the optimal solution. 3. 4 interviews spread over 5 hours, 2 coding, 1 behavioural, and 1 architecture. Coding interviews were pretty straightforward. The behavioural one was surprisingly easy to do, even for someone more introverted like me, this is because the interviewer had a very calming presence and the format was more like a conversation than a Q&A. The architecture interview was the most fun - I worked with a developer on a design problem for implementing a new widget. We talked about pros/cons, thought about how the implementation could be used, what edge cases to consider, and design decisions to make the solution more scalable and generalized.

Very academic, questions that either you knew the answer or not. The focus was not on thinking and problem solving. I believe the process favors recent grads over experienced engineers.
