What is this?
Unlike typical software engineer job interviews, front end interviews have less emphasis on algorithms and have more questions on intricate knowledge and expertise about the front end domain — HTML, CSS, JavaScript, just to name a few.
Many front end interviews are highly-focused on domain knowledge and applying them to real-world scenarios. You might find that grinding LeetCode is not all you need when it comes to interviewing for a front end position, but that's a good thing! Front end interviews tend to test concepts that are more practical and relevant to real world front end development. But that doesn't mean that you don't have to be familiar with basic data structures and algorithmic concepts - there's just less emphasis on them and you are probably going to get easier algorithmic questions.
