In the coding round, they gave you a scenario and let you pick a language to solve the problem. You choose your own IDE. The algorithm used is not hard but the scenario is a little mess and there are edge cases you need to find by yourself. In ML round, they just gave you a problem in 1-2 sentences, and you need to lead the conversation to solve the problem. It's open-ended and like the case study in DS interview, which does not require you to explain how to implement.
