My first interview in the London office was good. This was a 1 hour talk one-on-one about my CV, strengths, weaknesses, reasons for applying to the company and scheme etc as in any normal interview. There was also a case study to do with the amount of storage it would require to record every car journey in the UK in a month. Although this was quite difficult the interviewer helped me along the way and was generally very friendly and informative. I received generally positive feedback and after chasing up a couple of weeks later with many calls, I finally got through to the recruiter who said I had been invited to a second interview. The second interview was a shambles. Part of the feedback I got from from the first interview is that my CV/experience was well suited to the Data Analysis roles, and they'd try and find a relevant team senior person for the second interview. After another couple of weeks and calls every other day, I finally got through to the recuiter again who said they'd organised a slot for me, and this interview would involve a 15 min presentation on 'a complex problem'. Thats all the information I got. I sent numerous emails and calls asking for a bit more guidance, and also if there would be a whiteboard available, but got no response. I hoped for the best chose to present on a project I did for an internship during university. Fast forward to the interview and after being made to wait about half an hour after the start time, I was asked pretty much exactly the same questions to the first interview (I dont know why) by a recent graduate and a more senior manager. I was surprised to find out he was largely involved in Business Management, something I wasn't well suited for or was suggested for after the first interview. Nevertheless I went with it and the presentation went fine. The case study though was incredibly difficult. I was given 2 x A4 sheets of paper; a letter explaining the scenario and a sheet with roughly 100 bits of data. I was given 4 minutes to read the letter, all the information, come up with an argument to convince a business person to buy a product using all the data at your disposal. After the 4 minutes was up I had to do a role play with the senior person and convince them. I was overwhelmed by all the information, and this case study was far more difficult than the first. I read interview reviews on this site of people being asked to calculate the amount of tennis balls that would fit in a car, something that would be far easier. Overall the feedback I got was that I didnt have the commercial know-how they were looking for in a business consulting role (annoying seeing as my first interviewer suggested me for a data analysis role) and also that I struggled with the case study (which I guess is luck of the draw as to what type you get).
