The interviewer was unprepared, showed up late, and acted very informally. They had no idea who they were interviewing and had not read my resume. Only want to hear what they/he/she wanted to hear, and it felt like they were just had a bad day.

Met with the recruiter and the hiring manager but unfortunately I was not able to get past that round. Recruiter did say they will try to reach out again in the future so crossing my fingers I get another chance.

I had 5 interviews, these were with the recruiter, my line manager, line manager's peer, senior leader, then finally my manager's manager. In my experience, the interviews were mostly pretty simple.
