Ridiculously long interview process. Multiple hour-long in person interviews (I believe three), then a half day team interview. Given a very specific case study. AKA free consulting! All interviews were conducted offsite, until the final panel, where Sami (One of the founders) had all candidates come to the large, empty office to do the final case studies and redundant interviews. Having followed the company since my interview, they went from 20 employees to seven in a few months.
