I had an assessment centre for BP’s finance programme just before Christmas, but was unsuccessful (partly because I was exhausted from a 2-day A/C in Blackpool the day before!). Below is a summary of what happened.
My A/C was held at Beaumont House a hotel/conference centre on the edge of Great Windsor Park. Went to the meeting room, after checking in and settling into my room, around 6.30, for the introductions, presentation and run through the plan for the next day etc. Then off to the bar, and dinner before we left to our rooms we were given a case study to read through to help us the following day.
After breakfast and checking out we all met up in the meeting room for the day to begin. The day revolved around a fictitious oil company investigating oil production off the coast of a fictitious African country. The day was mainly group exercises, with two individual ones, each exercise will have its own case/briefing sheet. In the first exercise we had to do decide on different exploration options to find the best block of oil field to buy, second exercise we had to work in pairs to have a role-playing meeting to find out more information about different types of oil platform, then a group exercise to discuss our findings from the meetings and come to a decision.
After a quick lunch had to do a written report individually, for 1hr 15mins, deciding on the best course of action to take with a refinery in the UK given the case study for that exercise, then give a 10 minute presentation to an assessor on your findings and recommendations. My worst exercise of the day I think, atrocious time management from me, and left no time to run through in my mind what to say in the presentation (no separate prep-time for that part). Fourth exercise was a final group exercise to decide what to do with a surplus of 300 million gallons of gasoline.
Finally, I had a self-review exercise with one of the assessors, where I had to say what I did badly/well, what I had learned, what were best/worst parts of the day etc. At least it was a nice assessor guy doing it, which made it easier to be brutally honest about my performance. They do that exercise to test the competency of self-awareness and learning & development.
Hope that helps,
