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.

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
