DS&A questions. The interview is just that with only a couple of minutes of non-technical discussion. You need to be quick and fluent in standard LeetCode easy-medium problems, and have a decent enough grasp to come up with good ideas to approach LeetCode hards.

The focus was on DS&A. I was asked about how to merge three ordered arrays into an ordered array, and then how to generalise that for $k$ ordered arrays. It was okay, but you need to be faster and have the solution down as if you can do it in your sleep.
