I also sat for the test on the 8th so will try and answer your questions.
I’ve never seen any GMAT questions before so I’m not sure how similar they are. Apart from your normal percentage, ratio, proportion questions that you’d fine in SHL/Kenexa tests there was also a bit of geometry - eg. there was a question where knowing the formula for the area of a circle would have led straight to the answer. Basic probability and stats would also help - eg. there was question that asked how many handshakes would take place if 12 people at a conference all shook hands with each other person once.
But as it has already been mentioned, time management is key! We were also told at the beginning that we weren’t necessarily expected to finish all the questions so if you don’t know how to work out a question, or find that you are taking too long, just move on to the next. There were plenty of questions to be answered - 30 in 20 mins.
I heard back 3 days later.
Hope that helps and all the best
