I was given a basic telephone interview, then was given a video interview to perform. They asked several questions revolving around my experience with IT and some competency questions. Most was very basic stuff and general information can be found online. Id say don't stress over it and try and relax and be as confident as you can.

After a fairly standard application I had a video interview, this was a bit awkward as it consisted of pre recorded questions which you recorded your answers to. It felt a bit unnatural but ultimately went fine. I was then asked along to one of their assessment centres (I attended in London). Started with an introductory talk followed by a quick tour. There were three short assessments on maths, 'IT' and ven diagrams and set notation. The maths test is very basic and they give you a booklet about the ven diagrams but if its not something you've seen before they provide you with revision links that are quite good. The IT test was a bit odd, seemed like a general knowledge quiz come professional aptitude test. Questions ranged from what does HTML stand for to what would you do if one of your colleagues smelled really bad... After these I had three short (very short, maybe 5 mins) one-to-one interviews. I was offered the role but rejected it due to the lack of pay for at least 4 but up to 7 months!
