Humble Experience, you get what you put in!
Pros
Without a doubt a great place to cut your teeth or come in mid-level to learn a proven, enterprise wide sales methodology and with both some skill + dedicated effort you'll continue to earn more money each year. Uncapped commissions. Fun, but competitive work environment. Ability to submerse yourself across a variety of industries and build industry relationships with movers & shakers. If management and career advancement is on your mind, you can move rank quite fast for a 1,000+ person company after demonstrating success, professionalism, and not fighting the system. Work aside, rather young work enviroment so a good chance you'll build some good friendships and enjoy the typical Friday Happy Hour...if thats your thing :) If not, no worries.
Cons
If your lazy or don't like following a set system/framework, this is NOT for you. If you don't like change or are not versatile, this will not work. It can be a bit fast-paced with expectations high, but those who can keep up will reap the benefits. Product can sometimes be poor and even as a top performer if other departments don't pull their weight, you'll feel the effects. Starting salary can be a bit low for NYC standards but with performance you can demand a raise when justified.
