I interviewed at IBM (Portsmouth, South East England, England)
Interview
Classic CV submission, IPAT test, invitation for 1st round selection day - 2 group exercises + confirmatory IPAT test. The group exercises were the same ones as are discussed online - one logic (each of you has slightly different information) + one that is focused around organizing an event. Just do your best, focused on the team work and NOT solving it yourself (which would be way more efficient!!!!!)
The overall experience was pretty negative I must say - especially in comparison with other consulting companies/positions. Everything is very anonymous, people are not helpful at all when it comes to personal needs/preferences.
Interview questions [1]
Question 1
The confirmatory IPAT test only has the 'logical' part (i.e. the numerical series)
I applied online. The process took 3 weeks. I interviewed at IBM in May 2012
Interview
Group exercises- one logical one, one event planning task. Then a confirmation maths test.
The second stage was a one-to-one interview, case study and presentation (only in front of the assessor!) and group logic test (really hard)

Question 1
Why is the product so expensive? (I was trying to sell a mobile app to the interviewer)
