Application Process: I applied through my college campus selection. There were 150 applicants in the first round, 20 were shortlisted for the second round, and 10 made it to the third round. The interview panel consisted of 6 people, most of whom were very relaxed except for one.
Interview Rounds:
Round 1 - Technical Screening:
Questions Asked: The first round was a technical screening where they asked questions about data structures, algorithms, and problem-solving. Some of the questions included:
Explain the time complexity of a binary search.
Solve a problem involving dynamic programming.
Discuss your approach to optimizing a given piece of code.
Your Approach: I focused on explaining my thought process clearly and walked through each problem step-by-step. I made sure to optimize my solutions and discuss trade-offs where applicable.
Outcome: I was shortlisted for the next round along with 19 other candidates.
Round 2 - Technical Interview:
Questions Asked: This round was more in-depth, with questions on system design and real-world problem-solving. Some examples:
Design a scalable system for handling user sessions.
How would you improve the performance of a database query?
Solve a coding problem involving graphs.
Your Approach: I structured my answers using the STAR method (Situation, Task, Action, Result) for system design questions. For coding problems, I wrote clean, efficient code and explained my logic.
Outcome: I advanced to the final round with 9 other candidates.
Round 3 - Behavioral and Final Technical:
Questions Asked: This round combined behavioral and technical questions. Examples:
Tell me about a time you worked in a team under pressure.
How do you handle conflicting priorities?
Solve a problem involving multi-threading.
Your Approach: For behavioral questions, I shared specific examples from my past experiences. For the technical part, I ensured my code was thread-safe and discussed potential edge cases.
Outcome: The panel seemed satisfied, and I received positive feedback. However, I’m still awaiting the final results.
Preparation Tips:
Practice coding problems on platforms like LeetCode and HackerRank.
Review system design concepts and be ready to discuss trade-offs.
Prepare for behavioral questions using the STAR method.
Mock interviews with peers can help build confidence.
Conclusion:
Overall, the interview process was rigorous but well-structured. The panel was professional, and the questions were fair. If I could do anything differently, I would spend more time practicing system design scenarios. For future candidates, I’d recommend focusing on both technical depth and clear communication.
Application Process: I applied through my college campus selection. There were 3 rounds in total, with 150 applicants in the first round, 20 shortlisted for the second, and 10 for the third. The interview panel consisted of 6 people, most of whom were relaxed except one.
Interview Rounds:
Round 1 - Technical Screening:
Questions Asked: The round focused on core computer science concepts, including data structures, algorithms, and problem-solving. Some questions were scenario-based, like optimizing a given code snippet.
Your Approach: I focused on explaining my thought process clearly and writing clean, efficient code. For scenario-based questions, I broke down the problem into smaller parts before proposing a solution.
Outcome: I was shortlisted for the next round along with 19 others.
Round 2 - Technical Deep Dive:
Questions Asked: This round was more in-depth, with questions on system design, database optimization, and real-world problem-solving. One question involved designing a scalable system for a given use case.
Your Approach: I used a structured approach, starting with requirements gathering, then moving to high-level design, and finally diving into specifics like database schema and API design.
Outcome: I made it to the final round with 9 other candidates.
Round 3 - Behavioral and Technical Mix:
Questions Asked: This round combined technical questions with behavioral ones. For example, “How would you handle a disagreement with a teammate on a technical decision?” followed by a coding problem.
Your Approach: For behavioral questions, I used the STAR method to structure my answers. For the coding problem, I ensured my solution was both optimal and well-explained.
Outcome: I was selected for the role!
Preparation Tips:
Focus on mastering data structures and algorithms, as they form the backbone of the technical rounds.
Practice system design questions by breaking them down into manageable components.
For behavioral questions, prepare a few STAR-method stories in advance to showcase your problem-solving and teamwork skills.
Conclusion:
Overall, the interview process was challenging but well-structured. The panel was professional, and the questions were fair. I could have prepared more for the system design round, but my strong foundation in algorithms helped me through. My advice to future candidates is to practice consistently and stay calm during the interviews.
