LinkedIn Software Engineer interview experience

The overall difficulty felt genuinely hard, and the session included a modular inverse problem. There was also a problem that felt like a parity/PNC-style challenge, and I attempted it using a DP approach, but my solution ended up wrong.

I remember thinking about Fermat’s little theorem while working through it, because the modular arithmetic angle was clearly central. Even with effort, the hard questions pushed beyond what I was comfortable with under time pressure.

I didn’t get an offer. The experience left me feeling like the assessment measured not just coding speed, but whether the
