...all the advice for doing a remote job about bandwidth, tech (webcam, microphone, and headphones), and maintaining the space behind you...except that's all twice as important, at least.
Do not say that the thing that interests you the most about the job is the fact that it's remote or remote-friendly. If you're interviewing primarily because you want to transition into a remote situation, you should probably re-evaluate. At the very least figure out something else to say when asked why you're looking for a new job or why you're interested in the job you're interviewing for.
If asked if you've done remote or how you would prepare for remote, indicate you either have some experience with remote work (a freelance gig here or there will suffice) or are prepared to make the preparations necessary to be successful.
Know that working remotely is not necessarily a fix for being interrupted. If you're frustrated by the number of interruptions at your workplace, transitioning to a remote job isn't going to solve for that. I once had an interviewee mention his discontent with the number of interruptions at his current job. I asked how many times he was interrupted per day. He said four. I almost laughed out loud. I might have laughed out loud.
Those are the only remote-specific tips. Everything else applies to any interview. Do your homework. Be emotionally prepared, as much as possible. (I once had an interview that somehow turned into some kind of therapy session...I did not get that job, needless to say.) Have good questions about the company prepared, but also make sure they're appropriate; your questions about the company tell the interviewee as much about yourself as their questions to you do. Unless you're talking directly with an HR representative as part of the interview process, it is not the time to ask about benefits or other such details. You're there for the work; the money and benefits should, during the interview at least, not appear to be a factor. Don't be clever. For example, do ask, "What is your favorite thing about working there?" Do not ask "What is one thing you would change about the company?" Do ask about the business: competitors, market strategy, product direction. Do not ask about the business: what's the company's runway, profitability vs raising money, etc.
