      I interviewed at Sierra

      Interview

      The interview process consisted of an initial recruiter screen, followed by a coding interview and an onsite with multiple team members. The interviews covered technical problem solving, past experience, and general discussions about engineering and collaboration. The process was well organized and communication was timely throughout.

      Average interview

      Application

      I applied online. I interviewed at Sierra

      Interview

      Recruiter screen then take home then assessment, then onsite with debugging, take home assessment review and behavioural. Almost everyone I met was really nice and really easy to talk to aside from one interviewer who was late, spent the entire interview disengaged and seemingly doing other work and didn’t provide any extra time at the end despite the lateness. Genuinely would’ve been a great experience regardless of the outcome but that was the worst interview experience i’ve ever had. It really sucks spending so much time preparing only for an interviewer to treat you like you don’t matter : (
