When interviewing for a software engineering position at Facebook, the interviewer will ask various types of technical questions. These can range from very simple to very complex. Typically, the interviewer will start with simpler questions and progress to more complex ones. This indicates they are gaining confidence in your ability to do the job and are willing to explore your background in more detail. Regardless of their complexity, technical questions should always be answered briefly and to the point. You should anticipate follow-up questions any time you provide an answer to the interviewer.

"While JavaScript is widely used when creating web sites, it has its limitations. The language is single-threaded; therefore, concurrent or simultaneous operations are difficult to program. Web workers in HTML5 allow programmers to create scripts that run in the background and are invisible to the users. This is a workaround to executing multi-threaded application operations within JavaScript."
