Process
I applied online. The process took 3 months.
The interview process was lengthy, but a really great way to get to know the team and the company. The process consisted of:
- Three technical rounds
- One take-home test
- Two verbal interviews
The verbal challenges were fairly high level, and felt very much like a guided process where you were working together to formulate a solution, rather than being quizzed under pressure. Every interviewer was enthusiastic, patient and helpful.
