Interview process included 5 rounds (each of 1 hour) and an offline assignment. It was lengthy and tedious but mostly a positive experience. Only negative part was the overall duration from application submission to offer release - it took roughly 7 weeks.

Recruiter has no clue about the job. Very general screening. Hiring lead was mostly promoting himself, was not interested in my experience and skillset. The task seems like stealing you ideas to solve company's problems.
