Random walk question + dice question
Linear Algebra question, I was not able to get the question he asked and the interviewer got extremely upset because I couldnt answer it and hung up.
Classic recursion path problem and some stats question
Write a data-processing pipeline in python using e.g. pandas and scipy.
Coding was not really leetcode-style, more just problem-solving and implementing things creatively (more enjoyable imo). Deep knowledge of data structures is definitely helpful. Math stuff was brainteasers/probability questions - definitely pretty difficult, they're more concerned with the approach/thought process than an exact solution. Data science was just testing basic ML knowledge + implementation, understanding pitfalls/tradeoffs of your data.
