Good luck!

Wear a sleeveless or shirtsleeve top getting to the building and then put long sleeve top over for the interview. It’s extreme hot wave outside. But not inside (unless interview is outside which is unlikely). In fact it’s usually cold inside. If it’s not professional job, no dressing up is required but wear long sleeves.

You can have “don’t give a damn” attitude and just show up but it depends on how bad you need a job.
