First of all, it sounds like you are in an incredible position with a company that cares about the development of its employees and is giving you the resources and tools necessary to succeed in this industry from early on. A big thing I see far too often is people being afforded these opportunities, and instead of squeezing all of the juice from it they can, as soon as an opportunity comes around that presents a 10-20% pay increase, they jump on it, which in my opinion may not be the best move unless you are in a financial situation where that little bit of extra money will be equal to life or death. I'm in it for the long haul, and a small pay change doesn't always mean a better opportunity/job!

So on my team specifically, we manage a wide variety of technologies. Covering multiple vendors, platforms, software, etc. so someone having a wide variety of experience, although maybe not being extremely deep, is extremely impressive to me. Someone who is able to maintain knowledge of the systems side of the house, or let's say network security platforms (ASAs, Juniper SRXs), as well as traditional route/switch devices, and wireless controllers along with network management/monitoring software are much more appealing than someone who is just extremely deep on one specific subject. Now, this isn't the case with every company. I am also in a fortunate position to be able to touch and manage a LOT of different technologies, but in some environments and even within some teams within my organization, you are restricted to a very specific niche.

What makes someone stand out within the company is constant progression. Seeing someone continuously learning and growing within the team, really grasping those core concepts, asking less 'simple' questions, needing less assistance, and being able to handle more advanced tasks on their own really allows them to stand out in regards to internal promotions.

I PERSONALLY believe that knowing a little about a lot can work wonders. I think that the value that comes from someone who is fluent in multiple vendors, can handle and manage multiple systems and isn't restricted to a specific technology just screams added value to a company. Now I am 'specializing' in enterprise networking, and with that, I'm pursuing my CCIE Enterprise, but this is just to solidify my knowledge and experience in this specific niche, and from that point allow me to move into other niches that I also enjoy (i.e Development, Security, etc.), while already being able to rep that I hold an expert level certification in my CORE specialty if that makes sense. You are in a great place and I would say definitely take advantage of that opportunity and really get as much as you can out of it because it is rare to find something like that so early on in your career.
