Got contacted by a hiring agent after applying on the company website to take a IQ test. Passed that and was contacted again for a phone interview. The turn around time was fast. The phone interview is mostly technical questions as it is for a quantitative position. Make sure to know your basic statistical concepts like mean, standard deviation, etc... Also, make sure you know linear regression concepts. The interviewer was very nice and seemed very laid back.

30 mins phone interview and almost technical questions. I was invited to tell about the project I have done before and ask some questions regarding this project. Also, my programming language level was asked. There were also some standard technical questions like p-value, overfitting, cross-validation.
