I applied through college or university. The first round was held in mid-August, while the remaining rounds were conducted within a week.

There were a minimum of 3 rounds:

1. Aptitude + Technical This round was held via E-Litmus and covered basic questions related to quants, logical reasoning, and technical aptitude. Time is of utmost importance here.

2. Technical Interview This interview covered the fundamentals of almost every domain that you're supposed to know as a CSE graduate. They usually ask about your area of expertise and grill you on that, then slowly delve into other domains, especially DSA and OOPS. Having your basics clear is all they require.

3. HR Interview I cleared the Technical Interview and was immediately escorted for the HR interview. It was a fairly simple HR interview with the same usual questions, such as "tell me about yourself," "why BlackRock," "tell me about your college," etc.

I was asked to wait for a while. They conducted a few more HR rounds for some candidates, most probably to clear any doubts they might have about a candidate.

They selected 16 out of 40 students. Unfortunately, I was not one of them.

Sorting, Heap, Linked List, Tree Traversal, Abstract Class, etc.
