DTCC Programmer Trainee interview questions

Applied a year ago and was contacted by HR, had a phone screening then in person interview a week later. Interview went well, they didn't tell me I had to take an aptitude test that lasted an hour and a half, but I passed it. I didn't hear from them for 3 weeks and they contacted me again and asked if I was still interested. I went in again for another brief interview (20 min) and they called me an hour later and offered me the job.
