Interview
I applied online through LinkedIn and got selected for 1st tech round confirmation came via email, but did not qualify it to continue the next round.
The technical round was actually not that difficult but still I won't say it was easy in any way. Most things were basics to filter out lowballs, and then the a little advance topics were asked

I applied through a staffing agency. I interviewed at Cognizant (Tempe, AZ) in May 2026
Interview
Never got to the interview. They rescheduled 5+ times/were no shows at every interview I attended and claimed it was technical issues. This was all for some program where they train you to be a data engineer but it seems like they couldn't figure out an interview
it wasn't too difficult; there were about 3 rounds. There was an online assessment which included a multiple choice for technical and recorded video prompts for behavioral. Then there was an HR screening call and then technical interview with someone live.
