I attended the Launchpad event in October 2017. First you are put into groups of 6 and are given a case study, I won't bother giving details of this as it changes at every launchpad event, but you basically have a number of tasks to complete related to this case study, and you are given around 10-15 minutes to do each task. I wouldn't say this part of the assessment centre was too difficult, it was actually quite enjoyable. Next you have to do a written exercise. This was really very difficult, you are given a booklet of information, 10 minutes to read through it at the start, and then an hour to write a report. There was a LOT of information given in the booklet, it took me a while to to read and process all of it. I found the written exercise by far the hardest part of the day. Last is the actual interview with a partner, this was quite pleasant, my interviewer was very nice, the interview was around 20-30 minutes, and she asked me 5 'main' questions, though she also asked additional follow up questions after I answered each. The questions are pretty standard competency based ones, directly related to their behavioural capabilities, so I would recommend preparing examples for each of their behavioural capabilities.
