Phone screen with SWE even though it was for data science. The engineer talked about his experience and kept asking if I had any questions. He asked an easy coding question but explained it very poorly. I had to type what he said onto the screen to clarify. It wasn't just bad English. He defined terms in a contradictory way. The problem was easy but I was a bit jumbled by the bad explanation and kept thinking things were defined in the first way that he mentioned so I made a mistake. He was patient and pointed out the error and then I fixed it. They decided not to move forward. It was annoying since he asked a poor questions and that question had little to do with data science.

The entire interview process took about 4 weeks. I waited ~3 weeks for their reply. Setting up the on site interview was a bit difficult because the recruiter was very slow, plus they put me in touch with 2 recruiters so it was all a bit disorganized. The only information I got about the on-site was its duration, so I had no idea what would be the structure of the interview. Almost all interviewers were rude and uninterested, if you're having trouble answering the question they would start looking at the time or inspecting their fingernails. All in all, my worst interview experience so far!
