Meta Software Engineer Swe II interview questions

Got asked about my immigration intentions during the technical screen. Felt borderline illegal and very unprofessional. The interviewer was got visibly confused/upset at the answer I gave. On the technical side, it was a pretty standard screen, except they switched the problem if you already knew it well (I did for a few)

5 interviews with 2 sdi and 2 coding interviews plus a behavioural interview. I had a phone screaming interview with a decent level of complexity and no feedback at the end jus a rejection
