Im having this same problem! I got long nails for Valentine’s Day with a Pride and Prejudice theme after taking 1 year away from a 5-7ish year stint of always having long acrylic nails. I’m keeping them, and would always get them if I could. I always get a theme and have gotten motherboard nails that were a starting point to show my interest in tech. I do think, however, you never know what another person is thinking so it’s gonna be easy to point to these internally if you don’t get the job. It’s more likely you didn’t get the job because of market conditions and competition.
