I was contacted by a recruiting company that was working for Fidessa. It starts off with with a very simple 5 minute online timed quiz. Basically, the give you a small spinet of pseudo code and you are to state what output would be generated. It really just tests your understanding of conditional statements. The recruiting company stated that most of the people who have taken it have failed. Honestly, just breathe and figure out what the functions do first before looking at the if-statement. Once I passed that, I was given a phone interview with a person in the HR department. It's a pretty standard phone interview except she did ask a couple of technical questions. After going over my background, it was decided that they wanted me to be further along in my program and to keep in touch. If you get past this point though, you will take another assessment before scheduling an in person interview. This one is much longer and more thorough.
