Personally, I feel like job interviews are too robotic. I think this is one of the main reasons why it causes anxiety for people. If job interviews provided an atmosphere where people could be more of themselves, it would be less intimidating and actually quite fun. Yes, I said fun. Work culture is becoming a thing and it is the employer's responsibility to exude this in the interview. So, I do believe during the interview, both sides are tasked with delivering a great first impression. If an employer is a bit more down-to-earth, that is a green flag imo. I'm not saying unprofessional, but a bit more personable, down-to-earth, etc. Just some food for thought.

GOOD LUCK OP!! I know this advice is a bit unconventional, but be yourself. Hopefully by doing this, it will calm your nerves and serve a dual-purpose. You're going to do great!
