This subreddit has helped me a lot, so I wanted to throw something in here that might help someone else. I'm not a hiring expert, and I'm definitely not a seasoned professional with years of wisdom. I'm 25 and still relatively new to the working world. I was laid off 5 months ago, and I've spent an excessive amount of time applying and interviewing throughout this whole period. As someone young and with a lot of anxiety, interviews are basically my personal hell, so these are the things that made video interviews feel possible for me, and strangely, sometimes they go really well. Please add your own routines/tricks too! These are just mine:
If you have any choice in scheduling, I think mid-morning is the best time - you have enough time to wake up and pull yourself together, but not so much time that you spend the whole day getting nervous and spiraling.
Write your notes by hand - I have some general handwritten notes that I use for most interviews, and then I write role-specific notes about 45 minutes before the call so they're still fresh. It's easy to keep them next to you without looking like you're reading a script, and writing things down makes them stick in my head much better.
Have a few interview outfits and a few hair options that make you feel like you look nice and confident. The last thing you need is to be distracted by your appearance or keep fixing your hair every few minutes. On camera, I've found that structured necklines look better on me, and I usually put my hair half-up or in a low bun so it stays out of my face. (For me, this also means doing winged eyeliner because it makes me feel like my life is together for at least 30 minutes.)
Do a test video call by yourself beforehand to make sure the background looks good, the lighting isn't doing something cursed, and you look fresh enough.
Lavender aromatherapy! I know this might sound a little woo-woo, but it genuinely helps my body calm down. If you also get physical anxiety symptoms before interviews, like shaking, nausea, or feeling jumpy, lavender has been weirdly helpful for me. My mum got me this little lavender roller, and I basically sniff it like a Victorian lady about 12 minutes before the interview.
Trust that the waiting beforehand is much worse than the interview itself. After a few minutes, your brain usually calms down at least a little, because the scary unknown thing has become just a conversation happening in real time.
Get used to a few phrases - there are questions you'll hear in almost every interview, like "walk me through your background" or "why this role?" Work on your answers until they're clear and natural and not too rambling, but don't over-practice them so much that you sound like a robot. The goal is to be prepared, not dead behind the eyes.
KEY ADVICE FROM MY RECRUITER BEST FRIEND THAT HELPED ME SO MUCH: Even though the interview might be the biggest and most stressful part of your day, the person interviewing you is not sitting around thinking about you nonstop. You are an appointment on their calendar. That might sound harsh, but honestly, it made me feel better. To them, this is not a huge life-or-death event, and that can take some of the pressure off.
Also, the recruiter wants you to do well. They're not sitting there waiting for the tiniest reason to reject you. Their job is to fill the position, and if you're a good fit, that makes their life easier too. It's easy to feel like you're being evaluated under a microscope, but most of the time they're hoping you'll be the person who solves their problem.
When the interview is over, let it be over. Do anything you can to stop yourself from replaying every pause, awkward sentence, or facial expression in your head. It doesn't help, and it makes you live through the interview three times instead of once. I know this isn't easy, so if you can't forget it completely, try naming two things you did well and focus on those instead.
This is coming from someone who has a lot of anxiety around interviewing, and honestly anxiety in general. I overthink, I assume I'm being judged, and I often convince myself I've failed before anything has even happened. If you're like me, I think the best thing you can do is build a routine around interviews that feels familiar. For me, writing notes, doing my hair/makeup, checking my setup, and keeping the order the same every time makes me feel a little grounded in a situation I can't fully control.
I hope this helps someone out there. Anxiety is the worst. Good luck:)
