Arbor Research Collaborative for Health Database Developer interview questions

First-round was 30 mins call with HR knowing about the experiences from the past and present, just a basic call to touch base on what we have done so far to know if it's relevant to the job description. Second-round was 30mins call with the manager which had few technical questions about the current experiences. The third round was a video call with 3-4 people from the team which was all technical and lasted for almost 2hrs. A question was given 30mins before the interview started and had to be ready with the answers for the interview to begin. The interview went around mostly on that question and then stating personal technical experiences.
