Interview prep as a Frontend Dev?

After working for 2 years as a Frontend dev fresh out of college, I was looking to prep for a change now.

A lot of what I searched about frontend interviews involved JS/HTML/CSS and some framework-specific fundamentals which makes sense. However, I've also seen a lot about people brushing up on algorithms, practising leetcode which I found painful since it rarely pops up in actual work, if at all.

Any idea on what I should focus on? Or any help when navigating the interview process?
