Started by recruiter approaching me and scheduling a second round with senior sde.he was pretty uninterested and rude at the end he said i dont have time finish this and ask any question if u have or lets disconnect the tine was too rude and i felt sad but i finished the code due to that the only reason i disapprove nvidias interview is cuz of this guy or else if you get someone nice then maybe it could be better experience than the one i got.But a advice to whomever reading this never get depressed you can do it just i did even if i got rejected i did finish the code
