Look up popular interview questions ahead of time and think of ways to answer them, then practice giving the answers! You really can't practice enough- the more you do it, the more confident and prepared you'll be in the moment. Bring a copy or two of your resume, and paper to write notes on. At the top of your paper, list some of your accomplishments (to remind yourself if you blank in the moment).

When answering questions, be direct and give concrete examples whenever possible. Try not to ramble on or talk around the question.

If it's in person, get there a little early so you're not rushing in with sweat dripping down your brow lol. If it's online, login 5 minutes early to make sure the technology is working. Wear something professional (what this looks like will vary by job, but generally nothing too revealing or casual, like a t shirt and sneakers).

Remember that you are there to evaluate them just as much as they are evaluating you! Show that you're interested by looking into the company a bit beforehand, mentioning what you appreciate about their company values (or whatever), and having questions at the ready for the interviewers.
