I applied through a recruiter. The process took 3 weeks. I interviewed at Gambit Research (London, England) in Mar 2018
Interview
Preliminary Call - with one of the key members of the team, some stats questions, not so difficult, and it's smooth
Online Test - personally I don't like this kind of test and waste of time, but I got through this.
On-site interviews - meet all the team members, they are nice, the only compliant is that the questions sometimes not clearly addressed. It leads to some confusion. But it might be well-planned.
I would suggest the company should talk directly to the candidate. My recruiter is unresponsive and do not even send me a feedback at the beginning.
Thanks for the feedback. We're sorry that the agent took a while to get back to you. We'll certainly chat to our recruitment agents and remind them of the importance of being more prompt in communicating with candidates.
