Three parts: 1) Paper-coding an algorithm problem that you are interested in. You can choose any algorithm problem. 2) You will be asked about the details of one of your project experiences from your CV. 3) You will be given a paper of code snippets, find out as many errors in the code as you can.

In the first interview, they ask about your previous experience and have you review C# code. You are given a one-page document full of errors and code smells, and you need to identify them and explain how you would solve them. The full-day interview consists of multiple questions. These start with mathematically defining a booking matching problem, solving a book matching problem in less than a second (binary search), and then scaling it to more dimensions (k-d tree).
