athenahealth Sr. Software Engineer interview questions

Submitted my resume for a position listed on their website. Got contacted by a recruiter about 6-8 weeks later requesting a phone screen. Did the phone screen the following week where we talked about what the company is looking for and how I might fit in. After the call, I was e-mailed a "homework assignment" to complete and was told to take as long as I needed to. It was a fun challenge and I completed it the following week. The day after I submitted it, I got a thumbs up on my solution and they requested an on-site interview, which I did a week later. The on-site was about 6 hours at the Austin office. Two technical interviews about 90 minutes each, and two personal/cultural interviews at 60 minutes each. The technical interviews I brought my own laptop and used C++ to implement a solution for two different problems that were simple games. Neither problem was too difficult, but the limited time was a factor that made it somewhat stressful. After you complete the problem, they continue expanding on it if there's remaining time, asking you to make changes to make the games more complex.
