I applied through university. I interviewed at CareDash
Interview
1st Round: Phone/Skype General experience questions, silly brain teaser
2nd Round: Data exercise
3rd Round: Round of in-person interviews, filled with more silly brain teasers
They really like brain teasers, seemingly because they aren't quite sure how to ask actually useful interview questions. Memorize the answers for common google-able interview brain teasers and be ready to do some math for them.
Interview questions [1]
Question 1
What's the difference between a list and a dataframe in R?
I applied online. The process took 2 weeks. I interviewed at CareDash in Mar 2017
Interview
I applied online around the time of my graduation, and received a phone interview from one of the employees, which featured a few screening questions involving analytics and statistics. Despite my relative lack of experience in the field at the time, I moved on to the second round, where I was given a dataset and asked to answer a few questions. After completing this task and returning the test, I was declined after turning in that project.

How many gas stations would you estimate there to be in the United States?
I applied through a recruiter. The process took 1 week. I interviewed at CareDash (Cambridge, MA) in Nov 2016
Interview
Phone call, a problem set and then a skype interview. Everything took place within two weeks. I spoke with two people in their analytics team, they were both friendly and prepared, and spoke favorably about the company.
