The interview focused on core Java fundamentals, particularly threading (synchronization, deadlocks, thread pools) and processes, along with system architecture principles like microservices and design patterns. It included hands-on SQL questions on indexing, joins, and transactions, as well as in-depth Kafka topics such as consumer lag mitigation and exactly-once semantics—tying directly to my research project and production experience. The process concluded with a coding problem testing concurrency or Kafka implementation skills, emphasizing practical application over theory.

Interview Process Rating: ⭐⭐⭐⭐☆ (4/5) Interview Difficulty: Medium Interview Process: The interview process consisted of three rounds: Initial Screening (Phone/Online): A recruiter reached out to discuss my background and interests. Basic questions about my resume, availability, and salary expectations were covered. Technical Round: This was a hands-on technical test, focusing on algorithms and coding problems. I was asked to solve 2-3 problems in Java. It was challenging but fair, testing both technical skills and problem-solving ability. HR Round: This was more conversational, involving questions about my career goals, strengths and weaknesses, and alignment with the company's values. The HR personnel was friendly and provided insights into the company culture.
