Vantaggi
Depending on the group you join, you might learn a lot under a good manager, and have a great professional experience, like I had for the first several years at the company under my first manager. There are smart people. Your overall experience is kinda gonna be luck of the draw, but you could luck out. I made some really good friends there. Friendship that goes beyond the work tenure.
Svantaggi
* Rampant H-1B abuse - they hire people who don't have the concept of break points or debugging as software engineers, often times senior positions. Those salary should've gone to US educated grad. (The competent work visa holders are the most unfortunate ones, having to do multiple the work on a fraction of the salary and stick it out for many years before they can jump ship.) * Subpar hires leading to bad practice becoming the norm - spaghetti code in production is the norm. Testing in production just became the norm. People will run scripts that bombard the company's own servers and the whole thing always end up being a blame game where people who did nothing wrong end up having to not only work more to clean up other people's messes, but also somehow take the blame for it. * This vicious loop leads to a toxic culture, of blame casting, credit stealing, and offloading work to other people. Someone will make something that's not your problem your problem, and you need to do it, not as a favor, but to atone for a bogus problem that they created for you. Management repeatedly rewards those who screw other people to get ahead. Multiple complaints to management were not only unaddressed, but furthermore, covered up, unless employees go straight to hr. * Competent people who have a choice keep leaving, and the workload gets distributed to the rest of the competent employees who can actually do the work, and they inevitably leave too. It started out as a domino effect but in the past year or so has accelerated into a snowballing phenomenon.
