DataVisor interview questions

I went through one round of technical phone interview and seven rounds of onsite interviews with several engineers, a product manager and the co-founders. The interview questions test candidates on algorithms and background knowledge. For a few questions I did not come up with a viable solution within a few minute. The interviewers had an inspiring discussion with me, which led me to the final solution. I had lunch with a few engineers and they were super friendly. As they were planning to move to a new location, which was 3 minutes' walk from the old address, they also brought me to visit the new office after lunch. In general, I felt inspired and also well respected during the interview.

I was scheduled a phone interview after applying online. The interviewer called 45 mins after my schedule time and the recruiter sent an email notifying me of my rejection whilst I was in the middle of the interview.
