1,680 javascript engineer interview questions shared by candidates

One thing that stood out was the unexpected range of topics covered during the interview. While the role was for a Senior JavaScript Developer position, the interview went beyond just JavaScript and React, covering HTML, CSS, databases, AWS, and even backend technologies. One of the more surprising parts was that they had two exercises focused purely on JavaScript, which I answered correctly. Despite feeling confident about my answers and the positive feedback from the interviewers, I was shocked to learn later that I wasn’t selected for the role.
