Viator Senior Machine Learning Scientist interview questions

I want to share my experience with Gavin from TripAdvisor so that future candidates know what to expect. I heard back about a month after applying. The recruiter missed our first interview, then rescheduled but canceled again at the last minute. We finally managed to start the process on the third attempt. The interview had three stages, with reasonable technical questions. I felt the interviews went well. After the final round, I was told the next day that they were impressed and that they are preparing an offer which will come next week sharing the benefits. Next week they contacted me claiming there is a delay due to people being out of office. After following up a few, I was suddenly told they wouldn’t proceed with an offer the week after — citing suddenly negative feedback from my first interview that took place over a month earlier. This kind of turnaround was surprising and disappointing. Overall, it probably felt the most unprofessional recruitment experience I’ve ever had.
