Google SWE Intern interview questions

It was nice, the interviewers helped at points and the questions were tricky based on simple stuff but tricky in nature i had one question on dynamic programming and other on graph

In spring 2025, candidate “Alex” progressed through Google’s standard full-time SWE pipeline: a brief recruiter call to confirm role fit and schedule a 90-minute two-question online assessment; two back-to-back 45-minute Google Meet coding phone screens (one on serializing an N-ary tree, the other on array transformations); a “2 + 2” virtual on-site with two coding rounds (DP-based good-subsequence and heap-driven task-scheduler problems), a lite system-design exercise architecting a real-time step-tracking service for ten-million smartwatch users, and a Googliness-and-Leadership chat using STAR stories; followed by hiring-committee review, multi-week team-matching conversations (ultimately choosing Firebase Auth), and a final offer call detailing base, sign-on, and equity. Alex’s keys to success were six months of pattern-oriented LeetCode prep, disciplined think-aloud practice, and meticulous tracking of every interview milestone, though they would next time compress interview dates and rehearse system-design more intensively
