Google Interview Experience — Software Engineering Role

I recently had the opportunity to interview with Google for a Software Engineer position. The overall process was challenging yet incredibly insightful. Here's a brief overview of my experience:

1. Online Assessment (Round 1) The first round was an online coding test on HackerRank, consisting of 2 algorithmic problems. One involved dynamic programming (subarray optimization), and the other was based on graph traversal. I completed both within the time limit and ensured my solutions handled edge cases effectively.

2. Technical Interview 1 (Data Structures & Algorithms) This round focused on core DSA concepts. I was asked to design an algorithm to find the kth largest element in a stream and to optimize it for time complexity. The follow-up questions tested my knowledge of heaps and memory efficiency. The interviewer also discussed my approach to debugging and testing.

3. Technical Interview 2 (System Design + Coding) The second technical round was a mix of system design and implementation. I was asked to design a URL shortener like bit.ly. After discussing architecture, scalability, and database choices, I implemented a simple version in code. The interviewer appreciated my clear communication and structured thought process.

4. Behavioral / Googliness Round This round focused on my teamwork, problem-solving mindset, and leadership experience. Questions revolved around past projects, challenges faced, and how I approached learning new technologies. They assessed cultural fit and how I handled ambiguity.

Outcome: Although I didn’t make it to the final offer stage, the experience was incredibly enriching. It pushed me to strengthen my DSA fundamentals, system design thinking, and communication skills. The interviewers were friendly and provided constructive feedback, making it a great learning journey overall.
