I first spoke to a Senior VP. He seemed nice and it sounded like the work could potentially be a good fit. I then did an interview with a recent grad (note: I have 15 years of experience) which went horribly. They didn't understand anything that I said. They were horribly patronizing. They rejected all the experience that I described because it didn't fit into the entry-level tasks that they were expecting. Advice to management: Make sure that the interviewers are more qualified than the candidate.

Initial phone screen with 3 members of the team. A series of math and finance questions during the phone screen (very straightforward, about 10 questions in total). Then given a take-home data challenge (a former Kaggle competition), and prepare a presentation. Invited onsite. Onsite interview involved presenting the data challenge followed by another series of programming and math questions. Overall, interviews are very technical focused, which is great for a Data Science position. The group is young and there are many opportunities and amazing tasks coming in the pipeline.
