Applied through HR manager email, and forwarded to the recruiter. The recruiter contacted me for the 1st round of the interview, and took 2 weeks to schedule, it is 1.5 hour back to back phone interview with 3 people, 1 is statistician-technical questions, other 2 are managers. The statistics will test your about basic statistics knowledge, model assumption and GLM. Other two managers just asked about your experience in statistical modeling and internship experience, deal with big data problems. Overall is not bad, they are more like just writing down your words and took some notes.
