My experience in the interview was great! So once you pass all the tests provided by you before the face to face interview, my advice to you is to dress proper attire to be safe. Slacks and dress shirt will be fine. Be clean cut and be prepared for the face to face interview.
I met up with the hiring manager at Cracker Barrel and it was my first time having an interview at a Restaurant or Luncheon setting. So I did some research on how to have a proper interview session in a restaurant setting. It helped out a lot and gave me more confidence in the interview. Overall make sure you emphasize on your previous skills that you think will benefit the company. If he asks you if you have any questions about the company my tip for you is to keep asking him questions as if you visualize yourself that your already working there and any concerns you might come across from a technician standpoint in the company!
