The interview process is really fast, they got back to me in a couple of days after the application.
The process had 3 main parts
1. Screening phone call focusing on basic technical knowledge and a bit of an introduction on both sides
2. A programming homework which could be done in a couple of hours
3. About a half a day of pair coding with one of the lead engineers where we looked at my homework and worked together on several exercises and meeting the team
