Do your research before even accepting an interview at this place. Do not let them fool you, this is a door-to-door sales position with a salary based solely on commission and they will never give you a straight answer. The company has gone by several different names in the past few years, none of which are rated well and have poor reputations.
There are three interviews: a short in person interview, followed by an all day tag along with one of their salespeople, ending with a third in person interview.
Finally, they will ask for you to send an email answering three questions: What do you offer to NLC? Why are you the best candidate for the position? When can you start?
I received an offer the next day. It was a 15 page pdf that told me everything I already knew, providing no new information about what I would be doing. I told them that before I accepted the offer, I wanted some more information. I asked what I would be doing on a day to day basis, if there was an existing client base, and if any sick days, paid leave, or benefits were offered.
The next day I got a response ignoring my questions and retracting their offer saying that they made a mistake and we were not a good fit for each other.
