Wissen Infotech Software Engineer interview experience

The interview focus centered on the fundamentals I’d expect in Java: OOP concepts, data types and control flow, exception handling, the collections framework, multithreading, generics, and I/O. I remember it coming across as if they wanted to be sure the basics were solid before moving anywhere more advanced.

Overall, it felt like a straightforward emphasis on the Java programming core rather than a broad mix of unrelated topics. I didn’t receive an offer, but the feedback implied there was no shortcut around understanding core Java deeply.
