Pros
I know there's pockets of discontent and bliss at every company, especially in one that's international and 6k+ people. That was my thought going in after looking at the reviews on Glassdoor. So I took a chance and my immediate coworkers were great, but guarded. Also, the trade-off in a large company is you exchange A LOT of bureaucracy for the resources available: we onboarded a lot of neat software (not cheap) to make our lives easier and reduce "friction" in information flow, and improve analytics. So there's a current in the right direction. Also the company is doing some awesome stuff in Data Science, and Visualization. There's discretionary PTO + bonuses (if you negotiate for them upfront). There was always some kind of workshop too. A smaller company might not have all that. A big company also has a lot of talent, sometimes hiding under the radar to avoid politics. So good networking opportunities. There's a good program for vets to transition their leadership skills into the corp. life. Strong work/life balance and opportunities for charity work with coworkers and with voluntary PTO days. I know these reviews can make the whole company look a certain way, so take all this as one data point in the set.
Cons
Like the title says, there's a reason there's an exodus. I had 6 bosses in the course of 12 months. The people that were pulled into our area to "back-fill", left within 6 weeks ... every time, for 12 months straight. Sounds like WWI behavior, if you know your history. This is the 5th company I've been at in 16 years; I've never seen that kind of exodus. That being said. there are a lot of excellent people, with stellar work ethics and top-tier technical acumen, many where I worked with and was able to learn from. But the inability to coordinate across teams plagued every project. To be fair: I was only in one area but it connected across a lot of places. The products are really good and there's some cool tech being built, but the bureaucracy and guarded politics is suffocating. My guess is that some of the "politics" is just survival in corp. America. Just know that going in, like any large company. Also be advised, it's an open office with all the "collaboration" and noise. So: while all this may be a "con", it's a great opportunity some some clever leader to right a book about someday for "cultivating healthy culture". It's just going to be a while.
