Rochester Software Associates Software Developer Intern Java/Unix interview questions

Applied at career fair. Initial email was sent requesting logistical info like ability to travel downtown, salary expectations, knowledge of certain technologies. Had no telephonic round. Called directly onsite for hr and technical Interview one hour each. HR interview was standard hr fare. Pretty straight forward. Technical round was mostly Java interview questions because of the position. Static classes, final keyword, inheritance, abstract class vs interface, deep equivalence vs shell equivalence. Had a couple of code correction challenges related to synchronization. One relatively easy puzzle.
