Hopper Software Developer interview questions

First step is a 2 hour technical assessment, can be difficult to finish on time. Next stage is an hour with a senior engineer. Some behavioural questions and a coding problem loosely related to hopper and air travel. Difficulty similar to leetcode medium. On-site consists of 3 interviews similar to stage 2 and 1 purely behavioural interview.

The process is designed to select only the top performers in the industry. Had to spend a lot of time on the 4-5 interviews. The interviews themselves are purely technical. First you talk about your professional background and challenging problems you've experienced. The second part is an algorithmic task, which most of the time is not super challenging, but you have to be careful with the details.
