      Easy interview

      Application

      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
