A recruiter found me on LinkedIn and scheduled the interview.

The process consisted of two technical interviews, then a reliability test, and finally a personal interview with HR.

The first technical interview was with a Backend Team Lead and a Senior QA Automation Engineer.

The second technical interview was with the QA lead team lead and the same Backend Team Lead from the first technical interview.
