There were 2 pre-screening video calls along with a 4 day interview process with 2 days virtual and 2 days in person at their office with a group of candidates. They required multiple assessments as well as take home work during the process. Then did a group activity called the prisoners dilemma. I would not recommend them due to their main criteria being culture fit rather than experience, not including the time investment needed when interviewing 60-70 candidates and only selecting 15, your odds are very slim.
