Fairly simple. Applied for the role in December 2016, got a telephone interview within a week which was followed by a video interview that was most about FDM and IT industry and why you are suitable for it. I was invited to the assessment centre where we had four interview and four simple tests. when i say that the tests were simple.... i mean SIMPLE, which included a gcse level maths test, aptitude test, venn diagram and comprehension test.
