The process took about a month and I went through four different stages. The first was an introductory interview, which lasted about 30 minutes. The second was a take home test, of which you're expected to submit in two weeks. The third stage, was a technical interview with the engineering team where they ask questions around your submitted solution to see how well you understand your stuff. Finally, the last stage is a culture interview where you get to meet the CEO and talk more about yourself.
