Meta Data Scientist interview questions

It was a phone conversation with another Data Scientist. I was asked about technical background, previous experience, along with a task completed verbally over the phone. This was the first stage interview and lasted approximately 30 minutes.

Interview with the recruiter scheduled quickly. The recruiter was really friendly and provided some material to prep for the technical interview. The technical interview went well and the interviewer seemed to be in consensus with the solutions/answers. However, surprisingly shortly after received an email indicating not moving forward.
