Round by round

1. 1

   Technical Screening60 min

   The screening round was conducted by a PMTS/Tech Lead who wasted no time getting to the core of my algorithmic thinking. What I appreciated most was the practical approach, not just theoretical knowledge. The interviewer provided an online compiler and expected fully functional code, which felt much more realistic than whiteboard coding. Questions: Two well-chosen problems that tested different aspects of my DSA knowledge, medium-level array manipulation problem that required careful consideration of edge cases and other priority queue problem that tested my understanding of heap operations and their practical applications. Both problems required not just correct solutions, but efficient ones that could handle the various test cases thrown at them. The interviewer was thorough in testing different scenarios.

2. 2

   Advanced Coding Challenge60 min

   This round, led by an LMTS/SDE4, the interviewer had a keen eye for detail and wanted to see my thought process evolve from basic recursive solutions to optimized dynamic programming approaches. Coin Change Problem - Started with recursive approach, then optimized to DP. The interviewer was interested in seeing how I identified overlapping subproblems and built the optimal solution step by step. Minimum insertions to make string palindrome (modified version) - This was a tricky string manipulation problem that required understanding of longest common subsequence concepts and dynamic programming. The modification involved additional constraints that made the standard approach more complex.

   • Minimum insertions to make string palindrome
3. 3

   System Design60 min

   This was where things got really interesting. The interviewer first wanted to understand my recent project experience, then threw me into designing a distributed job scheduler - not exactly something I'd prepared for specifically, but the fundamentals I knew came in handy. Questions: Design a distributed job scheduler capable of handling high-throughput task processing. Started with basic architecture using Kafka for message queuing and appropriate database choices, then evolved the design as new requirements emerged. The interviewer was particularly interested in failure handling, scalability bottlenecks, and task prioritization mechanisms.

4. 4

   Technical Architecture Review60 min

   This round with a director was intellectually demanding in the best possible way. Rather than giving me a new problem to solve, they wanted to understand how I approach real-world engineering decisions. The detailed exploration of my project's architecture, the justification for technology choices, and the discussion of alternative designs felt like a masterclass in system thinking. Questions: Comprehensive architectural review of my recent project including:

   • Detailed explanation of system components and their interactions
   • Justification for specific technology choices and trade-offs made
   • Discussion of components designed by teammates and how they fit into the overall architecture
   • Exploration of alternative design approaches and their implications
5. 5

   Leadership and Behavioral Assessment60 min

   Two directors conducted this comprehensive behavioural interview, focusing on real-world leadership scenarios and professional growth. The questions were thoughtfully designed to understand not just what I've done, but how I think about challenges, conflicts, and team dynamics. Questions:

   1. What's your approach when you disagree with a technical decision made by someone more senior?
   2. How do you ensure code quality standards across your team?
   3. How do you prioritize technical debt versus new feature development?
   4. Tell me about a time when you had to deliver bad news to stakeholders
   5. What keeps you motivated in your day-to-day work?
   6. How do you handle design conflicts among multiple senior developers?
   7. Describe a situation where you had to learn a completely new technology under tight deadlines
   8. Share an experience where you mentored and led other developers
