Meta Software Developer interview questions

Was shortlisted after talking to them at the career fair and the recruiter was in touch throughout the process. Was called for a persona interview for 45 minutes. We talked about my past work for three minutes and then moved on to the coding question. Interviewer was helpful.

Since I had interviewed on-site before, they directly brought me on-site this time. I had 4 interviews: 1 behavior, 2 coding and 1 design. I have 12 years experience. All interviews went well in my mind, but surprisingly, no offer. No feedback given. I feel it was because one of the interviewers wasn't that nice and was quiet through most of the interview. While I wrote on the whiteboard and talked out loud, he was mostly on his laptop and barely responded. They tell you to think of the interviews as a discussion with a coworker. Well it was definitely not an engaging or pleasant coworker at all. Makes you wonder if the interviewer decided your fate as soon as he met you because he didn't like you. I have launched many successful products with many customers. None of that is taken into account in this kind of hiring process.
