They asked two LeetCode medium problems and reviewed my resume. One problem was a sliding window question, and the other was a graph problem. They also asked basic Operating System questions and inquired about the projects on my resume.

They started by sending me an online assessment (3 hours), which was followed by a behavioural "day in the life" (3 hours), and then a final round interview (behavioural and coding, 45-60 minutes).

I was asked a medium difficulty, LeetCode-style question: 'Course Schedule II'. I had to talk through time complexity (TC) and space complexity (SC), and answer further questions on more optimal solutions (if possible). Good experience.
