Brought into office with a sea of young faces as they only hire graduates and was told to wait in a room. First case study was unlike anything I had seen before but the general idea wasn't too difficult. I didn't think the interviewer explained it well; they just get their employees to conduct the interviews - no formal HR interview. There were two data sets that needed to be merged based on linked information, but the interviewer described it as 'transferring' data from one set to another rather than 'merge' or 'update'. After the first case study, I had to wait another 15mins before the second because my interviewer apparently had not yet printed out the case study (...). Second case study was pretty straightforward. Got sent home after the second case study. Interviewers were nice. Am surprised they didn't even offer a glass of water through the whole 2 hours I was there. They get so many new starters and turnover rate is so high that they don't really care about providing a good interview experience.

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.
