Try and keep your head up I’ve definitely been there before. It could have still gone good it’s always hard to gauge reactions and body language over video meetings. I’ve been at my current job for almost 4 years and I was a stuttering mess during my interview. Just try and remind yourself if this one doesn’t work out it wasn’t meant to be and you’ll find something right for you in time (hopefully very soon). I’ll keep my fingers crossed for you!
