LinkedIn AI Engineer interview questions

First, I went through recruiter screening, then I had a technical screening round where I was asked to code the KNearest Algorithm from scratch using python. Then I had 5 rounds in final loop - AI Coding Round, System Design Round, DSA round, AI/ML Round, Hiring Manager Round

Interview process was nice. First question was a coding question, second was just general knowledge of AI, CNNs, neural networks, explaining the fundamental concepts of a multi layer perceptron, etc. Cost function, back propogation
