CSG interview questions

got 4 recruitment process. first is recruiter interview (only asking about your experiences etc and explaining about the company). And the second is coding test. The coding test took focus on design patterns. and the last 2 of them are video interview. got rejected by the last video interview but got no meaningful feedback on why I got rejected.

We had an hour long interview where there was good back and forth with the ability to have time to ask all questions I had. Discussed job responsibilities, working environment, hours, management and coworkers
