Meta Machine Learning Engineer interview questions

45-minute one-on-one interview, two coding tasks (fairly easy), one question about the background, one about recent projects. The feedback was given the same day. Video call is setup via BlueJeans, coding is done via CoderPad.

Contacted by Facebook recruiter on LinkedIn. The interview was setup one month after. The recruiter called me, asked me how comfortable I was with programming, and sent me preparation material. Though the post was for ML software engineer, the expectation was for all engineers to program algorithms/data structures such as arrays, trees, quick sort, radix sort, heaps, hashes, etc.
