Average Neutral Hawthorne, CA

I went through a pretty standard pipeline where the early screen checked fundamentals and then the process moved quickly toward live coding. First was a 30-minute phone screen with basic DSA, then I had a 60-minute live coding session through Codility. After that, the onsite combined coding, system design, and behavioral questions, and it matched the stack they associated with the role—.NET and PostgreSQL. I left the whole day feeling like the difficulty was legitimate but coherent, like everything was pointing toward how I’d work in the real environment.

Difficult Positive Sunnyvale, CA

My process started with a recruiter call where we talked through my resume, but it quickly turned into a lot of in-depth technical details. After that, I went into a technical interview with an engineer that felt very LeetCode “hard”-style—more than I expected for an early step.

A couple stages later, there was an on-site that mixed technical work with behavioral conversations, running multiple rounds (around four to six). I remember the day feeling long, with back-to-back evaluation. After the interviews, the process went into the administrative steps: a background check, NDA paperwork, and then offer negotiation.
