Acturis Graduate Software Developer Interview interview questions

First part is going over 3 GMAT questions (I think they were ones I got wrong, 2 were straight forward but I needed a hint for one of them which didn't look good) I did not make it through to the PM interview because I took too long on the coding question which was about using an xPath Array to convert xml to strings, which was very weird to me, then some follow up questions on how we can optimise it for a specific case. It required the use of a HashMap (that's all I can remember). Worth looking into XML and xPath beforehand as they aren't very forgiving of simple mistakes. Interviewer was nice.
