Apple Machine Learning Engineer interview questions

Interview consisted of 2 phone screens. Started with DSA evaluation through shared CoderPad screen. Questions were leetcode medium level difficult. Asked about implementation of some ML concepts. The recruiter took over a month to follow up. Round 2 tested ML knowledge and past experience. The questions were testing core concepts and consisted involved discussion with the interviewer. I was able to get through most questions but probably the interviewer was looking for more in-depth explainations. I didn't make it to the onsite.

It was at a recruitment event on a school campus where the company had a recruitment event and interviewed a bunch of people. It was an interesting experience, I had not participated in similar events previously.
