Google Technical Support Engineer interview questions

Very hard DSA round. It was scheduled for a 1-hour interview, but the problem was much more involved and could easily take longer than the allotted time. The question required strong algorithmic thinking, careful handling of edge cases, and the ability to reason through complexity under pressure. It was not just about writing code quickly; the interviewer expected a clear approach, optimizations, and clean implementation despite the time constraint. Overall, it felt like a round designed to test depth in data structures and algorithms rather than a standard timed coding exercise.
