Google Interview Questions

Google's loop, as candidates report it, is front-loaded with coding. Of the 582 questions collected here, 306 come from technical screens and 203 from onsite rounds, with smaller online assessment and recruiter screen sets. Software Engineer is the dominant track at 322 questions, then Data Scientist at 145, Machine Learning Engineer at 37 and Product Manager at 30. Coding & Algorithms alone accounts for 233; Behavioral & Leadership adds 84, System Design 43, and Machine Learning, Analytics & Experimentation and Statistics & Math cover most of what remains. Difficulty splits 368 medium, 129 hard and 41 easy. Behavioral rounds are assessed on Googleyness. Coding prompts lean on interval reasoning: checking a new interval against existing ones for conflicts, computing the union of two sorted interval lists, assigning the minimum fleet to rental reservations. Recursion and parsing show up as depth-weighted sums over nested lists, and search-on-the-answer appears as maximising an equal wood segment length. System design runs to infrastructure, such as a large-scale polite web crawler. The behavioral set is narrative: working with a difficult colleague, describing a failure and what it changed, responding to hard feedback. 63 questions were added in the last 90 days, three are tagged as AI-assisted rounds, and 99 first-hand interview experiences are on the site.
