Bloomberg Developer interview questions

Has question about reversing the string and the words that occur in the string individually.

Bloomberg came to our school during our career fair. The whole interview process will require 3 days. Each day lasting about 30mins. The first two days they will give you riddles or a problem that you have to solve using a language you know or in C. The last interview is a HR interview. The first 2 interviews will be stressful, they are simulating the work conditions in the company. The last interview will be less stressful.
