      Performance Engineer Interview

      Apr 11, 2022
      Anonymous Interview Candidate
      No offer
      Negative experience
      Average interview

      Application

      I applied online. The process took 3 months. I interviewed at Mainspring Energy in Jan 2022

      Interview

      No offer after 3+ months, two 1:1 remote interviews, 5 in-person group interviews, personal presentation, & multiple in-person visits. Interviewers didn't seem particularly well-prepared and freestyled a bit, which made me question if they know themselves what exactly is the hiring criteria. Most strung along I've felt in an interview process in my career.
