BlackRock focuses on your resume, especially the projects you have mentioned. They will mainly ask about your contributions to the projects, why you chose them, and what real-life problems they solve.

Additionally, they may ask SQL queries (easy to medium, to me they asked 2nd highest sallery in employee table) and simple DSA questions (easy to medium).

This round is a combination of HR and technical, and it is based on your resume. In my college, almost everyone who cleared Round 1 eventually got selected (except me )😆
