Seems like they interview many people, but it was relatively quick. They focused a lot on how you handle high volume and high stress work environments. I was asked about the order of draw so know that!

Easy interview. Very short and typical of questions. I did not get asked to many questions because of it being entry level. Discussed the job in detail and expectations toward the company. I left feeling much better as it was not as difficult as anticipated.
