HR set up a phone screen unprepared and knows NOTHING about the job or the org, it was a complete waste of my time. To add salt to the injury, HR made me speak Chinese for the interview just because I am Chinese (Seriously?!). Absurd and extremely unprofessional. Avoid.
what is your goal for this job?
Initially, when I heard that the interview would be based on scikit-learn debugging, I got excited that they were asking more relevant questions for the role than just LeetCode. The interview had 10 debugging codes which nine of which related to the custom transformer. It was a closed book test with even disabled autocomplete. Candidates were expected to memorize all the details, method path, parameters, etc. I don't know how they wanted to gauge a candidate based on such a biased nonsense test. Just to add, HackerRank is awful. The instructions are not clear and Quanata didn't bother to share the constraints and instructions. You don't know what the platform looks like and what options are available for the test until you start the test.

Didn’t see how you can prepare beyond STAR stories of your past work on your resume. 2. Machine Learning: Was supposed to conceptual ML techniques questions but interviewer made it a case. 3. Business Case: Was supposed to be a case but it was just a discussion of my past experience. 4. Leadership: Typical behavior
