During an interview as a software engineer, you can anticipate that most questions will be technical or operational. The best way to prepare for this type of interview is to first research the company to understand their programming and the products they produce. Next, you should carefully review the processes you use as a software engineer to develop programs. Having a clear understanding of these will help you respond to any question the interviewer may ask.

"While JavaScript is widely used when creating websites, 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."
