Local perception is that Jana partners came in and wants to squeeze us for all we're worth then get out. Layoffs didn't hit Raleigh too hard (yet) but some of our work was transferred to other sites, so rather than having a tight knit local team, we're spread across time zones. That was the environment in my previous company and I don't prefer it. The small perks are going away little by little--many of us watched this happen at previous companies and we know that once cost cutting starts it usually never stops. Hopefully that won't happen here, but most of us assume it will. Insurance is still free but starting next year pays out virtually nothing until you hit a (middle range) deductible.
Overtime is generally expected. I sometimes get "vacation notices" for people who will be out of town for the weekend. A lot of people here are in the habit of working at least a little every day, and many of them work an excessive number of hours. Hard to say if it's expected by management or just a self-imposed drive to keep up with everyone else, but it's way more normal here than at my last company.
Adding a little bit to address my "culture" rating below. I gave it low marks because the culture of the company as a whole is "California". Everything is CA-centric, and there is little effort put into making the "satellite" sites integrate into the corporate whole. My previous company did a much better job of being a group of sites with similar culture throughout. Qualcomm is CA all the way, and CA values are often at the extreme of the values of the rest of the country (example, we hear about saving water constantly, when it's really only an issue in CA right now). The culture in Raleigh is mostly task oriented. We get along, we work together. We help each other out. It could be better but for the most part it's very good.
