it runs as the website states, you have to progress through the selection stages the final part if successful is a one to one interview lasting about 25 mins, you need to look at the website to learn about tfly and TUI as there are questions in the test and you can use a calculator for the maths questions, the 90 second presentation is fun and the day is quite relaxed! the usual group excercise is also in there. you need to have done some homework on the company but its not heavy weight stuff just go along be yourself and enjoy the experience, the recruiters are very friendly and relaxed (well i think we are, and we want you to succeed)
