The interview was very professional. There are a few things you should be aware of. Whenever a potential employer asks you if you are interested and if you can come in for an interview that day it means two things. 1) They need to fill slots so you have a very good chance at the job. 2) It's a test question to see if you are willing to come in on the spot. If you have the ability to do it, take the earliest appointment that day. It shows you not only want the job, you are willing to go the extra mile to get it. That being said the interview process was very quick. It took about half an hour for the interview itself. If you receive an offer you will move on quickly through the process. It takes about 3 business days roughly.
