Epic interview questions

Had a 4-hr assessment, an initial screening call by an existing employee along with him explaining about his work, final interview for 2.5 hours. Final interview consisted of two 30-min sessions about the roles, a 10-minute monologue about a topic of our choice, a 45-min case interview, and a final HR interview where they went over the details filled in the resume.

Started with a phone interview asking basic HR questions then sent an OA which takes 2-4 hours to do. The OA consisted of 4 leetcode style questions and some simulation parts. The leetcode questions are similar to whiteboard interview with no code editor or ability to run/test code.
