I found out about the position through a friend who forwarded me a posting on a social media site from his friend who works as a YSA. I emailed the hiring manager at noon on a Friday, had a phone interview at 4:30, and set up an in-person interview for the following Monday morning.
When I arrived I was met cordially and enthusiastically by Danielle, the sales administrator, and led to a glass-walled meeting room behind the sales floor. I was interviewed individually and successively by three people, a training manager and two sales managers. They were all fairly young, easygoing, yet serious professionals. The questions were pretty straightforward; know yourself well and you should be able to answer them honestly and easily.
I thought my interview went really well, and I got a reassuring "Wow, that was a good answer." at least twice from each interviewer. Unfortunately they emailed me two days later and told me that they "did not find a good fit between [my] background and the position for which we are currently hiring". I'm a little unclear as to what background they are looking for to fill entry-level sales positions, but hey, c'est la vie. Honestly, I probably didn't get hired because I answered the "Tell us why you're better than everyone else we've interviewed." in a non super-aggressive sales-pitchy way, which I was immediately kicking myself for as soon as I was two sentences in.
