The first round is about the machine learning knowledge, there are 2 interviewers from data science team and all of them are PhD. They ask me about my experience and projects on my resume. The question are very detail, and you need know very well about your project. They also introduce to me about what they do in the data science team. The second round is a coding interview. The interviewer ask me to write a specific class using python. I was not very familiar with the top programming, and the interviewer gave me an detail example and a lot of hints to guide me finish the process. The two rounds onsite interview and the interviewers are all very nice.

assume you have a 10 agents at a call center, your job is to prepare scripts for each agent and then find the best scripts that works for each customers. How could you design an experiment to test, later how could you design a system that leads each customer to best scripts, how could you evaluate the system and based on what metrics.
