Interview consisted 1 phone interview with recruiter, 2 technical phone interview, and onsite 5 hour interview including lunch before offer was presented. Recruiters were overall very transparent and easy to work with. There was also a small chat after offer was signed to then be assigned on a team. I don't remember much of the first phone interview, but it was pleasant. They will send you their engineering blog and also videos of the product at some point to look at. From there, you can get a better idea of the product and also the engineering culture. 2 phone interviews were over coderpad. Basic algorithms you can find on Hackerrank or Leetcode. I am entering as Front-End engineer so my interviews were all JavaScript based. I say study some basic algorithms, whatever language you picked, and get used to the coderpad. I accidently messed up the time of my interview and they were wonderful with it. The onsite consisted 4 interviews and 1 hour lunch. I got to see their building and interviewed with 4 engineering managers. They were all great and pleasant to talk to. 2 had some "white boarding" or coding and 2 had some architeture discussion. Culture fit seemed to be more important. I did just okay I felt like on the coding questions but all of the managers seemed layback and transparent with their feed back. I also had questions of my own since I've heard about the company growingfairly quickly. I wanted to know how they are planning to handle the work culture as they grow and also where they will fit all the new people? I felt they took the questions well and the managers all seemed passionate about their work. At the end the COO also popped in to say hello to me which was super nice of her! Overall I had a good experience interviewing with Compass.
