Pros
Nice campus, cafeteria, very nice co-workers, no layoffs during my time there, likeable and more transparent CEO, ambition to expand beyond connectors, secure in the market. I also have built a pretty good network of other engineers who have jumped ship!
Cons
Experience will vary by business unit and team you work in. I can confidently say that there is not a good growth mentality here, more a static mentality, so impending retirees or those not looking particularly for advancement should be happy, depending on manager of course. There is a good underlying philosophy handed down by Koch, though it is neither followed nor enforced amongst management, who are well protected by an impotent HR and their own cadres. You will notice an alarming lack of young employees, as lack of growth will be immediately evident. Interns in my department were not returning and were given rather boring tasks. Bonuses and raises are determined by value, though this will be mandated by managers, so obedience will generally be more valued than the profit you'll add to the company. Managers have also been caught fabricating the 360 reviews supposedly given by fellow coworkers. I've seen sponsored H1B employees (who their EE teams are now mostly made up of) get overworked, have their green card applications delayed, and also get well underpaid for their high qualifications (often with phds) and then vanish once their cards finally come through. So pay is low, benefits on par with a big company, raises and bonuses not guaranteed though generally paltry, and growth mentality entirely lacking. The regular outflow of young engineers should be expected, which has been observed and discussed not only in my business unit but across the company. Since I started at the team of around 20 EEs, there are exactly 2 others who are still there. And when I told them I was leaving, the first thing they did was justify the high turnover with the high demand for our skill set, which more explains why we can leave, not why we do leave.
