Amazon Software Development Engineer SDE I interview questions

3 hour interview - first round was behavioral and technical. For behavioral they asked about your resume and give you a time where you been challenged and how you overcame it. Technical part was merged intervals and LRU cache. Grind your leetcode 2 round was all technical- I forgot the first question but second second question was DFS flood fill (in some mine I believe) Third round was bar raiser - all behavioral. Get your stories aligned and don’t mention any metrics unless you can explain how you got your metrics for the results

The worst experience ever, facing two extremely difficult and mentally exhausting questions back to back, leaving me overwhelmed, frustrated, and completely drained of confidence, energy, and motivation to continue forward.
