The interview process consisted of a single technical round conducted virtually.
The interviewer started with basic Java concepts, then moved on to Java 8 (Streams & Collections), followed by a DSA problem, and ended with an SQL query.
The discussion was interactive, with follow-up questions on edge cases, time complexity, and approach.
