A classic leetcode question about a knight which needs to get from point A to point B (a DFS \ BFS search). I managed to describe the solution verbally, but the interviewers wanted a working code implementation without any option to google for syntax etc or using IDE. Just write code on notepad. I am still not sure whether he really expected it to work.
Given a binary tree, return parent node of 2 given nodes. Given a list of arrival times and departure times of busses, compute the least number of parking spots needed for the busses.
Basic ML questions and coding questions
What is the most exciting project you have done in the last year?
Round 1: Just questions about my background Round 2: Two leetcode-style questions. Don't remember the first, second one was merging an array of linked lists into one sorted linked list. Round 3: A lot of machine learning conceptual questions, especially about neural networks, when I'd use them and how I'd troubleshoot in different situations. Round 4: Reading through a paper. Nothing was exceptionally difficult, but it was tough to prep with how unorganized everything was.
