The interview process for the Software Developer Intern role at PayU started directly with technical rounds, with no online assessment.

Technical Interview 1 (45 Minutes): This round involved two medium-level DSA questions. Additionally, basic backend concepts like SDLC (Software Development Life Cycle) and SQL queries were discussed. The candidate cleared this round.

Technical Interview (DSA & Java Programming - Specific Questions Mentioned): Although not explicitly numbered as a separate round, key technical questions from an intern's experience were listed:

• DSA:
  • Reverse a Singly Linked List (explained pointer reversal approach and implemented it).
  • Implement Binary Search (walked through divide-and-conquer technique with code).
  • Merge Two Sorted Linked Lists (described merging logic and pointer movement in sorted order).
• Java Programming:
  • super keyword in Inheritance (explained its role in accessing parent class members).
  • Improving Design with Abstraction (shared examples of how abstraction leads to clean, scalable code).
  • Garbage Collection & Memory Leaks in Java (covered JVM's automatic memory management and causes of leaks).
  • Checked vs. Unchecked Exceptions (explained with real examples).

Technical Interview 2 (System Design Focus): This round focused on System Design. Discussions included batching logic, backend architecture components, and real-time use cases from previous experience.

Hiring Manager (HM) Round: Questions in this round focused on backend projects, experience working at previous companies (e.g., Juspay), and practical application of backend concepts.

Overall Experience: The candidate was selected for the role. Key takeaways highlighted were the importance of DSA, System Design, and practical projects for all roles. Backend candidates should expect architecture and database discussions.
