Applied through a recruitment agency and got called in for an interview about a week later. I got to the office about 20 mins early so had to wait for a little before being taken to another room to sit a problem solving, data sufficient and verbal reasoning test. The woman explaining the test was absolutely lovely, took her time, offered multiple times to bring me tea/coffee and asked me about my weekend. For all three tests combined I was given 30 mins to complete, which is just about enough time. The problem solving and data sufficient test were relatively straightforward. However, the verbal test comprised of a lengthy passage about something to do with caffeine, it was this test I completely failed, which I am not surprised by. There isn't really much prep you can do for any of these tests. Unfortunately, the pass mark was 18/23, I only got 17 and wasn't able to continue to the next stage of the interview.

Two stages, both general interview questions with a technical portion going through a case study. The first stage included 3 maths/logic based questions. Both interviewers were professional and I felt relaxed going through the case study with them.
