I received an unprompted email from a recruiter and after learning what the position was I agreed to interview. The first step was a 45 minute video interview where I was asked to write SQL code and answer a few case study type questions related to their products. The recruiter suggested I use R or Python instead of SQL for this step, but when I was asked the interview question it was very clear that SQL was the best choice of coding language to use. After this step I was brought on for an onsite which consisted of 4 different 30 minute interview rounds, each of which had a different focus (statistics, technical product sense, business product sense, and a SQL whiteboard coding interview). Recruiters were incredibly useful in providing information and preparing me for the interview. In hindsight I did not take enough advantage of the recruiters and the information they provided. I was treated really well throughout the process.
