The interview was a multistage process. Stages were usually couple days apart depending on interviewing developers schedule. Introduction, One-to-one short coding (relative to absolut path conversion), Two-to-one 4 hour coding with sprints simulation (extend a console based calculator), HR and culture fit talk and Finally a meeting with the CEO. It took couple of weeks. The CEO was hard to catch . I didn't accept the offer because the offered salary was too low. Otherwise, the company and people looked great.
