Pros
If you like this kind of life, it's a standard 9-6 culture reminiscent of the late 80s, one step short of punch clocks. Easily collect a mediocre paycheck by staring off into space or at your monitor-- most people will have no idea what you're doing. Massive infusion of cake, on a near daily basis… plus catered lunch scraps for you mid-afternoon carb scavengers. Free coffee. No nightmare administrative review process for "standard" increases. Nice walk around the campus. Their core business, if you care (I didn't) seems to be relatively strong.
Cons
I'm going to start by saying that I'm not a fan of corporate culture in general, however, Lennar Corporation takes a special spot in my opinion. The IT department (which I was in) is loaded with people who either do a lot of needless work, perform convoluted/outdated workflows, or don't work at all. Mostly the last one. But when "work" is actually done it can be defined as spending 2-4 hours writing long-winded passive aggressive emails with your bosses bosses mother in the CC line, undoubtedly combined with that personal sense of corporate "gotcha" satisfaction after they click Send. Then they go to lunch. The CIO tries, but she isn't really well liked (except maybe by the friends she stacked in upper management). It's not her fault that most of the suits are hoodwinked by these pseudo-sophistication trends where being day to day Apple hipsters somehow automatically transform you "an internet company". This translates to her engaging with her underlings in a flurry of PowerPoints and buzz word jargon where the end result is a magical techno-utopia that you're all working towards. I consider myself above average in tech, but listening to this is sort of like watching a Star Trek engineering scene where the warp reactor is about to go critical. As a department, IT is in about 200 different directions, none of which produce things of value. The over-investment of time into relatively mundane ventures, like getting ticketing systems to work or choosing "replacement" tools, makes this place a virtual museum of non-accomplishment and a case study in how throwing money and bodies at random projects is a good way to look busy but actually do nothing. Speaking of things with no value, Tuesdays are ITIL refresher day. We all looked forward to that one. Success here is generally defined as showing up to the pointless 2am conference calls with 30 or more insomniacs or weekend warriors, because something "really important" is happening. Most of this showboating could be accomplished with 30 lines of script code monitoring and notifying the appropriate parties, instead of a mass disruption of circadian rhythms. If you have anything remotely resembling talent, it's completely wasted at this company. Lacking talent though, this may be the job for you! If you can deal with the petty tweenager like drama that ensues on a near daily basis, you won't have to do any real work and if anyone asks, just tell them you're REALLY busy with whatever tech trend you saw on Twitter this morning.
