eBay interview questions

I’m not sure how I got this interview, as it was heavily focused on machine learning. It started with a hiring manager interview, where I was asked many in-depth questions, including how to choose a model, how to tune parameters, and how to evaluate model performance. I don’t have a strong background in machine learning, so I wasn’t able to answer many of the questions and didn’t move forward after the interview.

4 - 45 minute interviews. Only 3 of the 4 interviewers showed up. I emailed my recruiter 3 times about it and never got a reply. Of the 3 I had, 2 had live coding.
