i had an assesment day with data connection for the summer internship quite a while back…from what i can remember i couldnt do hardly any of the tests:P…they are meant to be challenging, but there were some ppl that found them ok so i guess it depends on the person! anyway, there was one sort of ‘IQ’ test one, which is just multiple choice looking at sequences and working out the next ones in the seqyence, looking at shapes, words that go together and odd ones out all that sort of things. Then there was a written problem about coming up with a simple communication system to solve a specific problem…the details and eveything else are explained clearly in the information they give you.
There was another problem solving exercise, which i found to be the toughest. It involved you following a piece of programming code and then writing down the output after each loop and then at the end summing them up together…but its more complicated than how ive just summarised as there are loads of nested if-else statements and functions within one another. the key to that is writing up a clear table of the values of each variable at the end of each loop so that if u lose ur way u dont have to start right at the beginning which I had to do. Then at the end of the exercises u have quite an informal ‘chat’ with an employee who goes through ur answers to the problems and its a good opportunity for u to say what you would do different next time (i had plenty to say on this!)
sorry if its all very fragmented and doesnt make much sense.dont really remember much. but i would just say, stay calm and relaxed and just think logically… its not that bad:)
