Coding test included how to split up rows of a table / dataframe across multiple processes and shuffling the data. High level code was ok, didn't have to be completely detailed. Another coding test was finding maximum depth of a binary tree.

Phone Screen: 1. Some question about BST (30mins) 2. SQL select/join (skip) 3. Maximum sum (5/10mins) Coding Round: 1 question - Every element repeats thrice except 1, find the element that is unique. Video Discussion: (With an architect from video encoding background) Asked me about different encoding schemes (not my specialty), how one would use cetain scheme, what is the benefit etc. Design auto thumbnail creation for titles in hotstar. ML Round: (with director of ML, Shangai/Beijing) This was the best interview so far, discussed on my strength areas - computer vision, new architectures for object detection, why they are better, what are the bottlenecks. Baeysian Probablity question which he came up with on the fly :) I struggled with the answer and he helped me with it. Hiring Manager/Lead Round: Did not happen
