[for meta === FaceBook] challenging as other reviews describe, quite messy and disorganised in my case. Got to the final stage but the management team decided to go with another candidate.

HR from the Meta wrote to me for a long time. I was busy with my current project, but after a while I accepted his offer and made an appointment with him. 30 minutes before the scheduled interview, he wrote me that he was not feeling well and asked to reschedule the call. I did it. 1 day before my next scheduled interview, I received an email that my interview was canceled. That's all. Are you kidding? From my perspective of view, it's really unprofessional.
