FDM Group interview questions

I had a video interview which had 4 questions, tell us about yourself, why do you want to work for FDM and two more I can't remember. Passed this, got called for assessment centre - there was an hour or so long talk which you could ask questions during, then three 5 minute 4 question interviews, all very quick-fire questions, some weird ones like Apple or Android? Asked about motivation for role is change at a company always a good thing? Then had 3 tests, Venn diagram test, Maths (GCSE level) and IT Aptitude test - 1 immediately after interview, the other 2 after lunch (wasn't provided, had to go out but you're in central London so plenty of places). About 80% of the questions across all the tests can be answered if you just work through the question, only a few in the IT Aptitude test required some background knowledge like what does SQL stand for. There was an office tour between the second and third test. Started 9 am left about 4 pm, so a long day. People there seemed pleasant and having fun whilst they worked. The offered salaries are very low especially if you get work in London where price of accommodation is huge (21.5k first year, 25k second year).

phone interview; there is a guy who will ask you how much you know their company. Then he will introduce this position, and most of time he talk a lot. Compared with him, i did not response so much. However, I still get a face-to-face interview.
