I had an HR interview, then a technical phone screen, and later multiple on-site interviews.

The on-site interview was probably my worst experience. The interviewers were not prepared; they were reading my resume in front of me and discovering things during the interview. They asked very basic questions like, "Oh! You currently work for Company X?" or "I see you have experience in A, but how about B or C?" The interview coordinator had no idea where some of the interviewers were. Out of four on-site interviews, two were telephonic, which defeats the purpose of having on-site interviews.

Interviewers were late for the interviews to the point that we had to reschedule for later that day. The coordinator didn't even care to learn my name and kept referring to me as "this guy" to other interviewers.

Another thing is that the company asks interviewers to input all information into some internal system, so every single interviewer came with a laptop. During the interview, they would simply start typing my answers. It was very distracting and didn't feel like a conversation.

After the on-site, I heard back from the recruiter. He arranged a phone chat with a few more hiring managers from different teams to see if I'd be a good fit for their team and if I would like the work the team had to offer.

Nothing major. Literally everything from my resume. In fact, in one interview, someone just asked me to read every single line on my resume and asked possibly two questions in 45 minutes.
