The interview was very quick and to the point, they moved very quickly with the hiring process. The first telephone interview consisted in a bunch of AWS related questions, a few architecture questions and a few motivational ones. After that there was a relatively easy coding challenge (read a big jsonl file, and create a website which would allow you to search through the file). The final interview was a face to face which consisted in software architecture questions, a math brain teaser and motivational ones.
