Easy questions. "How does a hash table work?" "What is the difference between inner and outer join?" "How do you use the Synchronized keyword in Java?" "What is the difference between REST and SOAP?" "Why would you use MongoDB vs. Oracle?" "What is ThreadLocal?"

Be careful about the Synchronized question, it was obvious that the interviewer didn't know about the java.util.concurrent package, so lecturing the interviewer about it won't get you any points.
