Overall, the interview itself wasn’t bad. The interviewer was fine, and the interview wasn’t particularly difficult. However, I encountered a very uncooperative recruiter, which made the overall interview process unpleasant. (They didn’t inform me in advance about a canceled schedule, so I had to reschedule, and despite me saying the proposed time didn’t work, they became unresponsive.) While the interview itself was not bad, the scheduling aspect made the overall experience feel unfriendly and frustrating.

The process took over a month (5 interviews / 1 interview per week). In the final stage, they informed me that they were considering me and another candidate, and then scheduled a final interview. In the end, they didn't choose either of us and reopened the position.

Waste of time and effort with huge assessment without interviewing! 48hrs of huge assessment and then will throw it at your face. and signing NDA for the project. don't enter the process unless agreed to get an interview to discuss your huge effort.
