This interview focuses heavily on behavioral questions, your familiarity with SQL, and your potential fit within their collaborative teams.

This visual timeline outlines the typical path a candidate takes from the initial application to the final offer. Understanding these stages allows you to pace your preparation, ensuring you focus on resume presentation early on and deep SQL and behavioral practice as you approach the primary interview stage.
