It's pretty clear to see upper management is looking to cash out by going public. Which translates to demanding from the top down to drive revenue, and profit margins above all else. Definitely, a crack the whip and work harder environment. If you are OT exempt, expect to constantly be asked to take on extra work and erode away your freetime. Vacation doesn't really exist here, it's more like comp. time, as you'll work close to 80 hours the week before and likely at least 60 after. Though you have some great people to work with, don't expect morale to be very high.
Training is really dependent on whoever they sucker in to be your trainer/mentor. They rarely take any load off the mentor, so it creates an unfair burden on them to train you on top of all their other responsibilities. From what I hear, they used to have a good training process that ended back in 2013.
Note: this does vary from group to group , but if you're in a revenue generating this seems to be the norm. Some of the none revenue seeking departments seem to enjoy their roles and atmosphere.
