I applied online. The process took 6 weeks. I interviewed at IBM (Londres, Inglaterra)
Interview
Online application form - standard questions.
Aptitude Tests - number series test was one of the hardest I've had to do, however numerical reasoning (felt easier than SHL or Kenexa) - but they have to be done consecutively no break.
Assessment centre was next step - employees were very friendly and engaging, it was a good experience - refreshments provided and the first half of the day involves two group exercises (planning event for client and logic problem) and confirmatory aptitude tests.
75% of candidates sent home at lunch - next part was lunch for successful candidates followed by a case study and presentation (in pairs) and an interview with the professional development manager (competency interview but make sure you have researched the company).
Interview questions [1]
Question 1
No particularly difficult questions. Remember in group exercises - be calm and confident and make sure to get in early as the good questions to ask will be used up very quickly. Finally stay alert and don't be too nervous, they just want you to give the best representation of yourself that you can, so believe in yourself and be you - if you get to the assessment centre you're already down to the last 30-40 out of hundreds, so they like you and want you to keep demonstrating you're the right candidate.
