Pros
The only pro about NEN is that you are able to drive a company vehicle around on a specified route and are generally unsupervised.
Cons
I worked at NEN full time for almost a year. I had two weeks of "training" from several different people who really had no idea what they were doing and i eventually had to learn how to do everything myself. When i told the territory manager of this problem he pretty much shrugged it off, he also had a hard time understanding English. I was given outdated route information, if i were to call a repair specialist for one of the machines he would either not answer the phone or be extremely disrespectful towards me to the point where i would just want to hang up, pretty much no help whatsoever with a "you can't fix it yourself?" attitude even though i had been on the job for less than a month, didn't receive ANY training on how to fix the machines, and didn't even receive the proper tools i needed to fix these machines from the company. I HAD TO BUY THE TOOLS MYSELF OUT OF POCKET. If you are going to work for NEN, be prepared for low pay (12$ an hour to do the amount of work that most people do for 18-20$ an hour), disrespect, and a generally unprofessional environment where "specialists" don't even understand what they are supposed to do.
