J'ai passé un entretien chez Mercury (Toronto, ON)
Entretien
The interview process is quite long, so be prepared to take a few hours off for the interviews. The technical part is not hard, but it is tricky, so make sure you ask all questions to understand the scenario.

J'ai postulé via la recommandation d'un employé. J'ai passé un entretien chez Mercury
Entretien
Couple rounds, one of which included some unsupervised coding time (after which you went over your solution with a interviewer)
Found the process pretty enjoyable, which isn’t something people often say about interviews.
