The online test was very difficult to complete in the given time, definitely prepare for it and be fast because you will likely not get to the end of it. Don't spend too much time on a question.. if you're struggling just move to the next.
Interview questions [1]
Question 1
Didn't pass the online test so can only speak for it. Questions to test your numeracy and reasoning such as: Classical logic questions like "A is taller than B, C is the tallest, D is between A and B etc.", visual questions of recognizing patterns, etc. Several examples and practice questions available online.
