The first round I only met with one person. It went well, so they invited me back to meet another 6 people. None of the 6 people knew anything about me, or which role I was even interviewing for. Be prepared to inform the employees why they are meeting with you. Once I made that my opening line, the meetings were much more productive.

Multiple rounds of interview, initially with HR and later with members of the team and hiring manager. Mix of technical and motivational questions. Final round also included a python interview.
