1st round interview was all technical questions about R. 2nd Interview was at the Boston office and consisted of a 2-on-1 interview with hiring manager and a presentation. The HR department is pretty disorganized here. Every candidate I spoke with had a different interview process which seems strange. I did not receive a single behavioral question during any part of the interview process. All technical questions regarding data programs (R, Python, VBA, SQL) and my experience with them.
