You can often identify the type of question you're being asked by how the interviewer asks it. When you hear a phrase such as 'walk me through the steps...,' you know that this is an operational question. The best way to respond to this sort of question is to break down the process into individual steps and briefly describe each one. The interviewer at Facebook will likely ask you a follow-up question so they can better understand your methodology, so come prepared with a few examples.

William Swansen

"I generally work in Ruby, so the first thing I do when building a single page application is diagram it based on the functional and non-functional requirements. I then search my libraries to see if I have code that I can apply to the application. Then, I write the code that I need to create the application according to the user specs. Finally, I test, debug, and finalize the application before publishing it. I create documentation throughout the process so other programmers can follow my steps and modify the application."
