I get the impulse behind trying to level employees but it always seemed ridiculous to me. Either you care about it enough to game it (which is pretty easy to do) or you don't an you just do what you think is important to you and your team and it works out... so you level up by accident.
This is actually a huge reason I don't like bigger companies. There is so much emphasis on Seniority, Levels etc. Its complete bullshit. You see people game the system, rise to the top, get all kinds of bullshit honors for doing bullshit things. Meanwhile the grunts doing all the actual work and innovating like crazy are just happy to make the higher ups look good in front of _their_ peers and don't really give a shit about the product or the market.... its a vicious, self-sustaining and self-dealing beast.
