Meta Software Developer interview questions

Got 2 question. One was about, given a string with parenthesis, remove minimum chat to make it balanced. And other was a hard question around divide and array into d partition such that the maximum sun is minimum.

I completed Meta’s full interview loop, investing significant time in preparation. I solved all coding questions optimally but found the time constraints too limiting. The behavioral and system design interviews were subjective, but I addressed all questions effectively. Some interviewers were professional, others disengaged. I didn’t pass, which is fair, but the lack of follow-up was disappointing. Despite my attempts to contact recruiters, I received no updates for weeks. This disregard for candidates' time made the experience one of the most unprofessional I’ve had. Many companies handle recruitment far better, and I’m disappointed in Meta’s approach.
