Difficult Negative United States

I went through a pretty intense sequence that started with two phone screens. The first was with the recruiter, then I met with the engineering manager. That manager conversation threw me off a bit because my lack of prior startup or Bay Area experience made the tone feel sharply critical rather than neutral. Even with that awkwardness, I kept going.

The technical screen was harder than I expected. I received a LeetCode-style problem categorized as a hard one, and I had under 45 minutes to solve it. The company’s reputation for tough interviews was clearly reflected in the format and pacing, and the whole experience felt stricter than what I’d seen at other large tech companies. After that, I moved to a final round described as a multi-round set of interviews that lasted about six hours, and the day overall felt like a test of endurance as much as problem-solving.
