Google Software Engineer interview questions

Good First, I need to find the value of gain K that gives exactly a 60° phase margin for: G(s) = 1.83/(s(s+2)(s+1)) For a phase margin of 60°, I need to find where the phase of G(jω) is -120° (since 180° - 60° = 120°). This system has: A pole at s = 0 (contributes -90° phase) A pole at s = -2 (contributes phase depending on frequency) A pole at s = -1 (contributes phase depending on frequency)

Coding assessment then four round onsite. Moved to team matching process after passing onsite, matched with second team I talked to after a few days, rejected from first team. All engineers and managers I talked to were really nice
