Marin Software Software Engineer interview questions

First was a 1on1 interview. I was just asked one question about a project in one of my courses. Then I was asked to write code for a problem on the whiteboard, it was fairly simple. There are multiple solutions but you should always do the most optimal one. About 1-2 weeks later, I was scheduled for a phone interview, questions were asked about the courses I took and some basic knowledge questions about them. I was then asked to solve a coding problem by talking about what approach to take, and giving detail towards how to code it. It was a simple problem.
