• We hire for ability, not credentials. You will notice that this is reflected in our recruiting process. The process is designed to test your ability to solve problems that you will face in the role you are applying for. There won’t be any brain teasers or anything else unrelated to what the job will be
• We invest tens of hours carefully crafting descriptions and the corresponding questions for each role. We spend so much time because we found this to be a good investment. These ads and their corresponding questions have proven to be an excellent filter. Make sure not to skip any questions – they are (by far) the most important part of the application
• If we like your answers, we will schedule the first interview. There are typically three interviews (+/-1) in total. For some roles, you may receive a take-home task that should take about 2-3 hours to complete. After that, we will ask you to work with us on a trial project for a week. We will pay you for this project. The idea is that you get to experience what it is like to work on our team, and we get a chance to experience what it would be like to have you as a colleague. Within that week, we will either make you an offer or let you know this is not a fit
• We keep this process to 2-3 weeks from when we get in touch with you
