Pros
Ink gives you the opportunity to learn and develop professionaly and personally. Flat hierarchy means that you can literally talk to anyone from managers to director or CEO at any time - and that everyone knows you by your name (yes, even CEO!). They are all involved in your development, and your targets are set so you can prove to yourself that anything is possible. So apart from doing the job and getting paid, you actually get commission on every single thing sold and they send you off on incentive trip (Rio, Texas, Cuba, Miami - to name few) very time you and your team have reached a quarterly target. Only sky is the limit!
Cons
Yes, it's hard work, but nothing was ever achieved by being lazy. If you want to succeed you need to make an effort.
