First round: Asked me to construct a python class to represent a polynomial (like a dictionary mapping powers to coefficients). And then write a couple functions operating on these polynomials, like a function to add two polynomials. Final Round: Two interviews were a mix of Leetcode and rapid fire questions (like difference between a linked list and array). Third interview was with the VP who asked about stuff on my resume and random CS questions like name a recursive data structure.

3 round process. 1st HR/behavioral, 2nd technical screen, 3rd virtual onsite. Focuses on prior experience, understanding of basic concepts like OOPS, multithreading, deadlocks, race conditions etc. Coding questions are leetcode medium level.
