Pros
You can get away with a lot, as long as you are billable. You can miss calls, take last minute PTO for multiple weeks, and be oblivious to the "tech" as long as you fit the persona this Company likes and rewards - Liars and cheaters. If you work here, you should make it your 2nd job; r/overemployed.
Cons
Career growth is pure politics. How many lunch and learns did you do? Did you set up a 100 person department meeting and show some tool you know nothing about? Promoted! Work hard at client billing more than 40 hours a week and get amazing feedback from the client: you get - "Get more involved in internal work". You can't win at this dump of a Company. It's pure nepotism and favoritism to move up or even transfer laterally. Office brown noses win. The general technical aptitude of most of the Consultants and Senior Consultants are outrageous. These people should not be in tech. Send them back to Big 4 audit/tax. Most Principles+ are dimwits that will just gaslight you, over and over. Leadership could not be more out of touch with reality, and they know this and don't care. Trying to transfer to a different office (while on a Global account, which is presumably easier) is like trying to get in bed with Dua Lipa, it's never gonna happen. You will meet and greet 20+ Senior Directors and up, all of them pretending to support you and your desired move. It's all garbage lip service. Getting anyone here to do 1 hour of "real work" is like trying to hit a golf ball on the moon. Qualitative BS > Quantitative Results. The Chicago office was bad, the Silicon Valley office and Seattle office were even worse. This place is JERK culture.
