I was referred by a friend who was a former employee. Everything seemed good in the first week. I passed the phone interview with some basic coding and algorithm questions.

But things started to fall apart when I tried to schedule the on-site interview. At first, I was expecting they would coordinate time slots or flight/hotel bookings with me, but neither happened. For a week, I couldn't even reach my recruiter by phone or email. I almost upset other recruiters because I couldn't settle my schedule. In the end, I had to prioritize other interviews and directly assign the date I was available to them. However, they then told me that they couldn't find a hotel. So, I had to book a motel myself and ask for reimbursement afterward.

The interview process only lasted 3 hours with 4 interviewers and ended before noon. Most questions were general coding and system design on a whiteboard. Though I feel the questions were less structured and focused compared to Google, Amazon, or Microsoft, it almost felt like they weren't sure what kind of candidate they were looking for.

Since the phone interview, I had had the impression that I would be working on machine learning in a data team. However, I learned on-site that the position I was interviewing for was essentially data processing. That's why, after the on-site interview, they arranged yet another phone interview with their machine learning team lead. A week later, I sent a follow-up email and was told that I was no longer being considered.
