Recently, I had the opportunity to interview with BlackRock for a technical role. The process consisted of two rounds – one technical and one managerial. Here’s a quick summary of my experience:
Round 1: Technical Interview
This round was focused on data structures, algorithms, and problem-solving. Some of the key questions I faced included:
Linked List: I was asked to implement and explain core operations and edge cases.
Spiral Matrix: A coding problem where I had to print a matrix in spiral order.
Binary Tree: Questions on traversal techniques and problem-solving using recursion and iteration.
SQL: Queries involving JOIN, GROUP BY, and handling real-time database scenarios.
Puzzles (from GeeksforGeeks): A couple of logic-based puzzles to test problem-solving skills and clarity of thought.
Overall, the interviewer was friendly and encouraged me to explain my thought process clearly.
Round 2: Managerial Interview
This was more of a techno-managerial discussion. The interviewer asked about:
My approach to solving problems when stuck.
How I would prioritize tasks in a high-pressure environment.
Some scenario-based problem-solving involving teamwork and deadlines.
A few follow-up questions on the coding round (like edge cases in linked list operations).
The focus was on communication, clarity, and decision-making rather than just coding.
Takeaways
Be thorough with data structures (Linked List, Trees, Matrices) and SQL basics.
Practice coding on platforms like LeetCode and GFG for puzzles and common problems.
Managerial rounds test your soft skills, ownership, and mindset just as much as your technical knowledge.
Overall, it was a great learning experience, and I found the interviewers very approachable and insightful.
