Mainly behavioral questions. Describe a time you faced a difficult situation.... Most of the questions started with management type questions. How many people you managed, etc.? The role did not ask for any management experience. Although I did. I quickly adapted to the questions. Have you ever done natural language processing (NLP)? I answered, some but nothing production capable. Well that's 50% of this job. If its 50%, why am I here? My resume did not have anything about NLP, and the job description had one line about it. Amazing. Then some more behavioral questions, and how you ever used <insert app name>?
