Apple Research Scientist interview questions

Asked many basic Machine Learning concepts , like what is the difference between logistic regression and SVM, which one is more robust to outliers? And several Deep Learning related concepts, like which is relu, what is sigmoid, when dropout is used, etc.

Got an email from one colleague of hiring manager first and talked to him that day about interest etc. Then had an interview for around 45 minutes with the hiring manager - digging deeper on some of my technical work. I followed up with her after 10 days, she said they want to invite me on-site. Heard from Recruiter after another 4 days (and another reminder from hiring manager to her) - got scheduled to visit 2 weeks later. In between no response from the recruiter about any feedback on the technical presentation I was supposed to give - so I emailed the hiring manager directly. Interview Day Started with a brief HR interview with the recruiter for around half an hour followed by an hour for my technical talk. Then six separate 45-minute interviews with teammates of the hiring manager (there was lunchtime in between - with the hiring manager). I thought it went well. Everyone seemed nice friendly and passionate about what they are doing. Asked recruiter after a week - she said they remain interested and get back in few weeks - three weeks later she said I was a good fit but not a great fit. I think lot/most people who may make it to the on-site stage could be a good fit but many other factors (including internal) may finally determine the outcome. Just be yourself and honest with whatever you say.
