Summary
I interviewed for an Associate C++ Developer role at BlackRock, navigating through technical discussions, a DSA problem, a low-level design round for a cache system, and behavioral questions before receiving an offer.
Full Experience
A recruiter from BlackRock reached out to me regarding a C++ Developer role. We had an initial discussion, and it took about 3 weeks to complete the entire interview process.
Round 1: Core + DSA
Technical Discussion: The interviewer delved into modern C++ concepts, focusing on topics such as move semantics, smart pointers, and polymorphism, requiring a detailed explanation and understanding of each.
DSA Problem: Towards the end of the round (last 15 minutes), I was asked to solve 739. Daily Temperatures. I implemented the solution and discussed the time and space complexity.
Round 2: LLD (Low-Level Design)
Low Levl Design: I was asked to design a cache system. The discussion also involved different cache eviction policies, such as LRU (Least Recently Used) and LFU (Least Frequently Used), and how they would be implemented in the system.
Round 3: Behavioral
Scenario-Based Question: The interviewer asked a few behavioral questions, including scenario-based questions and motivations for applying to BlackRock.
