"fast-paced environment" means getting shit done. it means rolling hard like facebook, google, zynga, groupon, etc. it means launching fast. it means getting feedback fast. it means failing fast. it means the exact opposite of the folks complaining about it who work at ibm or hp or microsoft or yahoo or aol. or worse yet, some hole-in-the-wall enterprise vendor inflating internal budgets and wallowing in mediocrity.
fast-paced to me means "if you can't keep up, don't step up."
regardless, if you have to ask, it's not a place for you to work.
