When people talk about Big Tech—Google, Amazon, Apple, Meta, Microsoft—they usually also talk about LeetCode. They talk about getting lucky or unlucky on the Q3 and Q4 on CodeSignal.

tl;dr: he’s a student, recruiter noticed he’s side project, he got offered an internship, no LeetCode or technical interview
