I applied online. The process took 2 months. I interviewed at Swiss Re (Telford, England) in May 2015
Interview
Standard online application, Telephone interview and then assessment day which consisted of, group tasks, psychometric tests, one on one interview and a 10 min presentation.
I really enjoyed the assessment day, the staff were friendly and lunch was included. I think what they really look for is how well you work in a team and how you present yourself.
The whole process too about 2 months. Applied in April and heard back about 2 weeks later for the telephone interview, then assessment day was about a month later. Got the offer about 1 week later. (1st week in June)
