The interview process was moderately challenging. It started with a Java technical task using Java 17 and Maven, requiring live coding and debugging while sharing the screen on Teams. The second part focused on soft skills, discussing teamwork, problem-solving, and communication. Overall, it tested both technical expertise and collaboration skills.
