Experience:

This experience details an interview for a Senior Software Engineer — Frontend position, focusing on problem-solving and architectural thinking across three diverse rounds.

Round 1: Live Coding — Building a Movie Search Component: This round tested UI/UX craftsmanship and JavaScript fluency. The problem statement required building a movie search component with several requirements: rendering an unstyled list of movies, implementing real-time search using substring matching, adding basic styling to display movies as cards, enabling genre-based filtering, and supporting subsequence matching (e.g., "hp" should match "Harry Potter"). The candidate's approach involved fetching movie data on page load, storing it in memory, creating input boxes and dropdowns with event listeners, and implementing filtering logic using JavaScript loops and conditionals.

Round 2: System Design — Building Excel from Scratch: This was an intense and thought-provoking system design session. The interviewer asked the candidate to design an Excel-like spreadsheet application, with a strong focus on data structures and performance.

Round 3: Hiring Manager Round — Deep Dive into Experience: This final round was more relaxed and conversational. It focused on the candidate's experience, technical ownership, and collaboration with cross-functional teams. Discussions included key achievements in previous roles (performance, scalability, UX improvements), responsibilities in current company (frontend architecture, performance optimizations, backend team collaboration), and follow-up technical questions on mentioned projects to understand the thought process behind technical decisions.
