Acumen Data and Policy Analyst Statistical Programmer interview questions

Found the job opening on my campus recruitment site. Submitted an application online through the Acumen website and received an email within a week to schedule a phone interview (which would be a few weeks later). Phone interview was about 30 minutes long, pretty informal, just going through my resume and research experience and why I wanted to work at Acumen specifically (make sure you have a good answer for that). Had to describe the data analysis, in detail, that I had done in the past. Heard back a week or two later when they requested that I fly out for an in-person interview. Only offered to reimburse $400, which covered about 2/3 of the cost of the trip. Interview was about 5 hours. Began with a very easy logic/stat test, kind of like the SAT/GRE. Didn't need that much stat knowledge beyond the basics. Then moved on to a series of 5 interviews, one of which was held casually over lunch. Everyone was very nice and smart. Asked questions about my research experience, why I wanted to work there, and what interested me about data analytics. Intellectual curiosity, a desire to continue learning after college, and some computer competencies, were I think the main things they were looking for. Didn't need a huge interest in policy. Overall, a nice place with smart, motivated people. Projects seem interesting with a lot of room to grow over the first couple of years. Definitely wish they had reimbursed fully and offered a higher salary.
