Lambda Machine Learning Engineer Intern interview questions

First there were 2 interviews to get to know you and talk about your interests and backgrounds to see if you’re a good fit. I was also told what they were looking for so there were no questions what I’d be doing in the company. The third interview was after taking a 2 hour technical coding challenge where I had to fit a model to the coco dataset and optimize it. The interview would’ve been about my solution to the challenge but I didn’t continue with the interview process due to accepting another offer.
