Rivian Machine Learning Engineer interview questions

The process was as follows: Recruiter Screen -> Coding Round -> Onsite Panel (4 rounds). All within one month. Online coding round was Leetcode. Panel was C++ coding. 3x Technical Deep Dive Interview didn't seem very well aligned to check the right skills. Python and C++ rounds but not very focussed on particular language. Deep dive had random questions with very less correlation. Rather a conversation would have presented better opportunity to express skills.
