I applied through a recruiter. The process took 3 weeks. I interviewed at Ipsos
Interview
Recruiter interview with two recruiters, interview with hiring manager, assignment that had to be completed within a week. Overall pretty straightforward, however it took awhile for them to get back to me (around 2 weeks) and they didn't provide feedback.
