If you’re legitimately a good candidate, find confidence in knowing you are who they should hire. Don’t necessarily say that, but believe in yourself. Look up some common behavioral/situational interview questions and have some general answers queued up and ready. I always expect these. They put you on the spot to come up a situation that pertains to their question and when you’re nervous, that Ivan be tough. Idk what the job is, but I think all this applies to any job interview I’ve ever had. Just find a place of confidence that you’re comfortable coming from and prepare because that preparation will result in perceived confidence. Again, believe in you and your value and go be your best you. If you don’t get the job, that’s okay. It isn’t a reflection on you. There are a lot of factors and you can only control what you’re able to. Gear up and prepare for the next one. Good luck!
