This is an example of a hybrid technical and operational question. While technical questions asked during an interview at Facebook you will be quizzed about specific concepts, operational questions explore how you do your job. This question first asks you to define how a specific concept impacts your program and then discuss how to remediate it. As with technical questions, hybrid or operational questions should be answered briefly and to the point.

"An OutOfMemoryError is created by the JVM when there is no memory available for it to use. This will result in a program halting. The simple way to fix this is to allocate more memory to run in the java application."
