Hr is super nice, and discussed a lot details with me. The first round is with manager and another senior data scientist. They asked some detailed question about my previous experience and project.

I received an email from the recruiter asking about some behavioural questions and past experience (the type of questions you typically request over the phone). I replied with elaborate answers and later in the week received a phone call asking exactly the same things. I received a rejection email 2 or 3 weeks later with no explanations
