I really enjoyed the overall interview process and it is very well thought. All the discussions are related to the role and very close to what a data scientist does day to day. There were total 4 rounds and 1 screening round. Final discussion was with the recruitment team.

This was one of the worst interviews I've been to. The interview process really shows their culture. It involved 10 rounds, which felt very unprofessional and was a really long process.

Technical Coding Behavioral
This was a pretty bad interview process. The recruiter missed the first virtual screening interview and only got in touch 40 minutes late. Despite this bad start, I got to the final onsite stage. During the onsite, they talked a lot about the company culture, but I never got any feedback on my performance, even though I spent all day interviewing. I think this is disrespectful, especially since they talked so much about their values.
