I got an interview at the campus career fair and an on-campus interview afterward. At the career fair, the employer asked me some basic questions in OOP and Java, such as the difference between an abstract class and an interface, and some Big O notations for sorting. A little bit of system-level knowledge was included, such as the stack during recursion.

Nothing unexpected. I found an error in a page of Java code. The errors I found were an uninitialized variable and some errors in a loop at edge conditions.

A question using binary search.
