I was contacted by a recruiter via LinkedIn. I had an initial phone interview covering ML concepts and coding. According to the recruiter, it went so well that they did not require another one.

I was then invited to the campus for an onsite interview, which I can describe as more of a torture than an interview. It started around 9:30 am and lasted until 5 pm, with a total of seven interviews in one day.

The interview process was unstructured. I was interviewing for a data science/software engineering position. The questions were open-ended. Some interviewers focused on math/theory, some on high-level software design, and others were unclear. It was difficult to determine what each interviewer was looking for and how to formulate a proper answer. One interviewer was rather rude, despite being 15-20 minutes late for the interview. Overall, it was not a good experience. The campus and food were great, though.

A few days later, I received a call from the recruiter. "Your interview went well, but we couldn't find any position for you. I tried to find a team by passing your resume over, but unfortunately, we don't have an open position at the time!" A simple question for them: Why do you interview people then? Why do you waste people's time by sending a bunch of bogus job opening messages over and over?

Interestingly, after the onsite interview and while I was waiting for feedback, another LinkedIn recruiter contacted me about an open engineering position at LinkedIn.

Simple but open-ended questions
