Consist of many interviews, screening with HR, interview with hiring manager, call with HR, interview with system engineering managers, network engineers, producers. Followed by call with HR. HR asked if I need visa sponsorship, I have said yes. Then he said that company will sponsorship. This happened every time I spoke with HR, they made impression that they are very tentative to provide sponsorship or budget is very limited. Network engineering team unable to ask complex enough question to check my knowledge. Asked less than ten questions in total. Producers demonstrated that they have very limited knowledge on network engineering even after many years (>8) of working there. Also let know that time to time demand too much.
