Pros
There are a lot of smart engineers and technical managers at IGT. Within the narrow confines of the hardware and software that IGT is concerned with, you can learn a lot. There is a cafeteria (I never went) and a free gym (I never went). While there is no official compensation for overtime for salaried employees, managers will try to offer some kind of off-the-books time off to people who have to put in a lot of extra hours.
Cons
Hoo boy, where to start... IGT is a company that innovated its way to 70% market share in the industry, got complacent, bloated up, and started losing market share fast. The management team from the glory days is long gone, the folks at the top seem to be generic suits these days, with all of the leadership acumen that that implies. Advancement as an engineer is possible, but difficult. Overtime is frequent and required. Layoffs were very common when management realized that market share was slipping, stabilized as IGT share stabilized, and have recently (March, 2014) started again. Just before the layoffs began again, the company rolled out a major branding campaign: "Out of the Blue." The gist of which seemed to be, "Blue is Good." I wonder how many of us would still be employed if the money for that campaign had been spent on salaries for the people who actually make the companies products. To close, I will re-iterate the warning that others have posted: Do not accept the Restricted Stock Unit grants. IGT can and WILL enforce the non-compete clause in that agreement even if you are laid off. I have worked 10 of the last 12 years in the gaming industry, and I cannot get a job in Reno because I am forbidden from working in the gaming industry for a year after I was laid off. All because I took 1/4 of one grant of stock. For 50 shares of a declining stock, I am losing a year's employment.
