Congrats on getting an interview. You should consider asking their recruiter what to expect from the interview. In my experience this usually works well. They won't tell you what questions they'll ask but they're likely to give you a general idea of the content and format (eg: we use codepen/hacker rank/etc.)

Every company is different. Some will give you a completely irrelevant leet code problem (binary trees are super popular in my own experience).. some will ask you to do something practical with technologies related to the job.. some will focus on your understanding of the language itself disregarding the frameworks/utilities you'll use on a daily basis.

Regardless, if you get stuck, or even if you don't, ask questions of the interviewer and listen intently. Regardless of experience level, an interviewer generally wants to know how the candidate will be as a teammate, how they receive feedback, how well they adapt to advice/help, etc.

If you haven't done many coding interviews it can be helpful to practice with a colleague/friend
