**Company**: Facebook **Location**: Menlo Park, CA **Role**: Research Scientist **Level**: Entry Level **When did you have this interview?**: Last Month This is about the first screening interview for FB research. **What kind of technical questions did you get asked?** Asked about myself and my recent research. Explain my research. Then asked an algorithm question to summarize of few "friend" tables.

2 problems. The second is 1D candy crush. I have not played that game so I understood the question wrong, guessing it only need to crush once. No reminder until when to run examples at the end of the interview.

The question is not so hard and I did pretty well. But the HR contacted me later and did not get to the next stage due to lack of headcount.

I took the phone interview at FB, which included two Leetcode problems (easy/medium) level, with big(O) follow up. No resume went through or other stuff, only the algorithm problems were asked. Overall it felt good, the interviewer gave hints when I stuck.

Had an initial phone screen for their research scientist position which is a 1 hour long screening. The interviewer jumped right into the interview and the first was a LC medium question which had to be solved within 20-25 mins since the second part was an applied stats questions on expectation and cdf, pdf derivations. The last part was supposed to be an applied ML question. For my part, took me quite a while for the stats question with lots of hints since my stats knowledge on pdf to cdf and expectation was a bit rusty. Overall seemed like a reasonable process if you prepare a little with the stats basics and practice some probability puzzles.

2 rounds of coding interviews, two leetcode coding questions per interview. 2 rounds of system design interviews. One general system design and one in domain system design. 1 round of behavioral interview
