With some exceptions, Netchex suffers from upper-mid to mid-level management growth issues. Seemingly, this is company-wide, though some departments seemed to have been adapting well. The department I was in hasn't - yet.
The current problem, as I had come to see it, stems from having a mixture of both promoted and direct hired leadership at the department level. To even reach this point, it was something that played out over the past couple years (i.e. growth issues), but I don't want to get into the details.
At this time, there is really more of a reformist agenda going on throughout that department (perhaps all departments) that is fairly ridge and yet still vague. Until that's cleared up (which I presume will be another year) I wouldn't recommend taking on this company with any other mentality then to use them as a stepping stone in your career.
I'll add that in my individual experience, after that first year, I felt under-utilized and greatly inhibited. I had gained infrequent, little sense of achievement; and at points, I had lost total confidence in the department, and the products we've built, maintained and planned to build. I had lost confidence with the company on occasion, and I had even lost confidence in myself and my choices. This isn't necessarily something that will translate over to your experience should you go with Netchex, but I don't think was a unique experience. You'll do fine if you don't really hold high value and expectation on those things, which goes back to my recommendation on your mentality going in.
There's a lot more to be said, but I have to keep some material for my book. I'm joking... but maybe.
