I applied through a recruiter. The process took 3 months. I interviewed at Pymetrics (London, England) in Sep 2018
Interview
Recruiter Outreach, Assignments, Talks. Fairly long but as pymetrics massively recruits, it seems selection and assessment was key
First off a discussion with who would be my future manager
2 assignments and interviews that are simulations of routine tasks on the job
Talks with top management
