I interviewed for three rounds. First round is screening interview. They asked about basic NLP and machine learning questions. Second round is technical interview with more detailed questions on machine learning, scripting. The third round is technical challenge, with 48 hours for an NLP problem and 24 hours for two Java programming questions.

Apply on nuance or linkedin, one telephonic round with HR and then with a team of 2 people, one is a manager and another is an NLP Research Engineer. Generally 1 hr.
