I interviewed for a software engineer role at Fiserv. The process included a recruiter call, a virtual interview with an engineering director, and a final onsite round at the King of Prussia office. The onsite lasted around 2.5 hours and included multiple panel interviews. Questions were mostly around my resume, Java/Spring Boot, backend APIs, microservices, databases, debugging, system design basics, and behavioral/team-fit topics.

Java generics, agile scrum, unit testing
