Google SWE Phone Screen: Python Patterns to Master in 45 Minutes

FAQ

Is it better to show an O(N) solution even if I’m not 100 % confident?
Yes. Google judges correctness first; an incomplete but correct O(N) pattern beats a perfect but buggy O(N²) one.

Do I need to know advanced Python libraries like functools.lru_cache for a phone screen?
Not required. The panel’s judgment in the 2023 Search loop was that “not an exotic library—but a clear caching pattern” sufficed.

What compensation can I expect if I advance past the phone screen?
For a 2024 SWE L4 hire, the base is typically $185,000 – $190,000, with 0.04 % equity and a $20,000 sign‑on bonus.
