Technical Round (did not advance) I didn’t clear the first technical round, but these were the key questions: Top-K Frequent Elements Implement a function to return the top K most frequent integers in an array. Explain the approach and why it’s optimal. Extension: handle a streaming input. I discussed an event-driven, chunked approach—processing counts per chunk and updating/replacing a rolling top-K across chunks. setTimeout Ordering with an API Call Given a setTimeout followed by an API call, identify the issue with execution order and make the API call run after the timeout. I talked through the call stack, event loop, macro/microtask queues, and how Promise/async-await can control ordering. Remove Overlapping Time Windows For input like [[3,2],[1,6],[4,8],[5,9]], remove overlaps to produce something like [[3,6],[4,8],[5,9]]. They wanted a step-by-step plan: input sanitization, processing strategy, and analysis of time/space complexity. Reason : The response/feedback i got was your answers were right but from data persepective they were not thorough
