It is best to know someone to get an interview. Just find someone on Linkedin and ask them if you can put them as a reference. Just beware they will ask you how you know them. Just make something up.
After you apply on their website (they're always hiring), you will get a phone call to set up an interview. The interview process is different every time. Sometimes you just have a one on one interview and you're done, sometimes you have the one on one then a board interview, and sometimes they do a speed dating type of interview.
They will ask very basic interview questions:
-Tell me about the first time you sold something
-What's your best quality
-What's your worst quality
-Are you comfortable making 80 calls and 200 minutes on the phone every day
-What experience do you have
-Tell me about a time where you were challenged and how you overcame it
-Tell me a joke
