I applied through a staffing agency. The process took 4 days. I interviewed at Bayer (Cambridge, England) in Feb 2016
Interview
Overall 4 stage interview (including those of the recruitment agency), so pretty demanding. Phone interview, assessment day, face to face interview at the company, dinner and discussion with the company and final assessment day, including group tasks-presentation-interviews. I made it until the final stage with 6 remaining candidates.
