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, while others were 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.

• List merging
• String pattern matching
