Unrealistic quota goals. Every single month feels like it's end of quarter, and end of quarters feel like end of year. End of year is just insane. The pressure every single month is tough to deal with and especially in ESMB, quotas are just not realistic. Big deals tough to come by.

The culture in the NYC office is nothing like the other offices. When there are events or happy hours, everyone is too busy or exhausted to even go. Very much a heads down and focus kind of atmosphere.
Path to promotion is VERY political. Be prepared to play the game to move up.
