I had screening interview with the recruiter and follow up interview with the manager. After I had 5 panels, each 45 minutes 1 on 1. It was more conversational interviews without dedicated coding or system design questions. Some questions was really junior level, like what types of db joins you know. There were also small coding assignments and language/framework specific questions, i.e how rate limiting works in springboot. Overall impression - some interviewers were not prepared to conduct interviews overall, by asking only specific to their current project related questions.
