I applied online and received a phone call a week after, I was then invited to do a video interview where you are asked pre-recorded questions and have about 60 seconds to record your answers. After passing the video interview I was invited for to an assessment centre in London which entails 3 short interviews and 4 tests. The interviews each had about 4-6 questions where the interviewers do not prompt you for answers, so they can last between 10-20 minutes depending on the level of detail you give, so make sure you include as much detail as possible, use examples and make it relevant to the stream you are applying for. This is a strength-based interview. Tests: Venn diagrams and set notation: this involves shading regions or write the outcome of the shaded region. You will be given links to prepare for this which will be enough Aptitude test: a variety of logic questions, business questions and IT questions, IT acronyms, programming. Nothing too difficult, this one you cannot really prepare for however look at some IT terms. Maths Test: GCSE maths, arithmetic calculations, Pythagorean Theorem, simultaneous equations, fractions and percentages, you will be given links. Verbal Reasoning: requires you to read through a passage and answer questions e.g. whether the information presented is either true, false or cannot say.
