I applied through a campus recruiter. The recruiter was very nice and arranged the phone interview very soon.
The phone interview was 45 minutes. First, the interviewer very briefly asked about my background (about 2 minutes?), then moved to the coding test. The coding question was not hard. I gave a simple solution first, but the interviewer asked if I could improve it. Then I gave a better solution. It sounds like the interviewer was satisfied with the second one.
For the last 5 minutes, the interviewer asked me if I had any questions. I said no.
The question was pretty straightforward. Given a random number generator and an array consisting of M numbers, generate a number from 1 to N that is not in that array.
The following metrics were computed from 1 interview experience for the Meta Quantitative Engineering role in Canada.
Meta's interview process for their Quantitative Engineering roles in Canada is extremely selective, failing the vast majority of engineers.
Candidates reported having mixed feelings for Meta's Quantitative Engineering interview process in Canada.
