Vigorous, with a number of tests to get an idea of what kind of person I was. Felt lengthy but I felt was good in that the company got to get an in depth insight about me before the interview. Although the position I interviewed for I didn't get, the recruiter at Kallidus thought I'd be better suited in another similar vacancy which in the end I got. Best thing was I didn't have to go through the tests again, just talk to the Line manager hiring.
