C3 AI Machine Learning Engineer interview questions

A mail with a hackerrank coding questions. There was 3 leetcode style question (1 easy and 2 medium I would say), and a multiple choice question part with plenty of machine learning related questions

They schedule 30 mins of the first round with one of their senior data scientist. I think then move to onsite if they give a pass. The first round is not techinical, they want to check your explainability because one of their important jobs is to explain how the ML model works to the customers.
