The interviews are divided into 3 parts. First, there is a short phone screen. Followed by a more technical interview with the senior engineer. There is a short HackerRank question with easy difficulty. Some raw SQL coding exercises. And review some code to guess the intent of the coder and try to fix what you can. You will then be given a coding challenge to do at home. Once the process is completed, you will be invited to talk with CTO to discuss some work history and given a short overview of the group interview.
The last interview will have you do a 30 minute rounds with various team members with some technical questions to test your knowledge.
The interviewers were very forthcoming and inform you along the way what general area will be covered so you will never step in blind.
