I met Athenahealth recruiters at a college career fair my university hosted. After a good chat about myself and the company I was offered an interview the next day (standard for this career fair). It was mostly technical and I was given a fairly simple hackerrank problem to work through. As is common with code during an interview it was more there to allow the interviewer to see how I worked than to test my coding abilities (although I imagine if I couldn't write anything in my chosen language that would have been a deal breaker). No need to impress them by picking a complex or obscure language I did it in python and that worked just fine. I completed the challenge fairly quickly and we went on to some problem extensions. Later that week I was called to schedule an interview day where they would pay for my travel out to their Waltham office. This didn't end up happening due to COVID-19 and I was able to reschedule at a time that worked for me for a series of online interviews. Again, about a week later, maybe a bit less I was contacted with an offer for an internship which I accepted.
