Average Negative United States

I went through a recruiter call and then a few technical rounds, and the whole vibe felt hostile and disrespectful of my time. Even when the interviewers were outwardly neutral, it never really felt like there was much respect for the effort it takes to sit through multiple steps. The hardest part was that I didn’t get any clear feedback on why I was rejected, so I was left trying to guess where things went wrong.

The technical loop felt brutal in a very specific way: debugging and system design were both high-pressure, and missing even one detail in the debugging work meant the round could effectively be over. System design also came with frequent interruptions, with the interviewer pushing for quick, confident answers to the point where you couldn’t just reason through ideas slowly—you had to have the basics down and respond fast. I also felt like some parts weren’t transparent, so I never fully understood what they expected beyond the general requirements.

Average Positive San Francisco, CA

My path started with a recruiter touchpoint, then I moved into live technical rounds that felt like they were testing engineering thinking more than memorized trivia. The format included coding and debugging, and the tasks were realistic in the sense that I was building or fixing concrete behavior—there were API-style problems and debugging through failing tests, not just pure algorithm drills.

System design was where the experience became inconsistent. I remember one interviewer being very engaged in earlier rounds, but the system design discussion still felt off-balance. Even when I tried to clarify scope and expected behavior, I got vague responses or a “what do you think?” kind of answer. That made it harder to land on the right assumptions, and it noticeably soured the momentum I’d built in the coding and debugging parts.
