Nuance interview questions

First HR phone screened, then got 3 interviews with 3 different teams at Nuance. The first one entirely focused on the questions about programming languages theories and how each language is compiled and executed. Interviewers thought my answers are too general. The second one is pretty chilled, the interviewer just asked some questions based on my resume and gave me a programming test to do. I did not finished as he had to go for a meeting. The third interview starts with some behavioural questions focused on my past internship experience, and the technical part combines both writing algorithms on a white-broad and taking a programming quiz, all questions are not hard, and interviewers are pretty nice and patient since they let me finished my quiz with no rush.
