Interview
Round 1: Online Assessment
3 DSA problems (1 easy, 2 medium), similar to LeetCode.
Round 2: Technical Interview
Started with introduction and detailed discussion about my internship work and project architecture. The interviewer was an experienced Java developer, so we had a deep conversation on Spring Boot.
Topics discussed:
@Controller vs @RestController
MVC pattern
Then moved to DSA problem-solving:
- Find pairs whose sum is a multiple of 6
- Count occurrences of each string
- Count palindromic subsequences

Round 3 is System Design, where you design scalable systems and explain architecture. Round 4 is the HR round, which evaluates communication, behavior, and cultural fit within the company.
