I applied online. The process took 4 weeks.

Recruiter call, then take home online assessment, then hiring manager. The take home online assessment was a waste of time. Any company who provides that should be banned. They exploit the time for the interviewee. Even though it was a medium level problem, they shouldn't test someone with take home assessment, as with ChatGPT anyone is a programmer nowadays.

After passing the take home assessment there was the hiring manager round. The hiring manager was extremely incompetent in terms of technical knowledge. I don't know how he managed to get that job. I felt like they already hired for that position and just wanted to waste time.

Some LC medium, it requires sliding window to solve.
