I applied through a recruiter. The process took four weeks.

The interview process consisted of one live coding session, where they allow you to use your own IDE without AI, and I used Snack Expo. There was one system design interview and one discussion with two managers. Everyone was very polite throughout the process. My recruiter was extremely responsive. Whenever I had a question, he replied quickly and was always available to jump on a call when needed.

If a user clicks a button multiple times and sends multiple requests with the same payload, how should the backend handle that situation?
