The management at Sarnova only cares about one thing, and that's saving money. Whether that means depriving their employees of opportunities for growth by keeping the headcount stagnant or severely underpaying them, I can guarantee you will likely not get paid your market value by working here.
Furthermore, if you're looking for a place with cultural diversity, Sarnova is, most certainly, not the place to be. Not only is there a lack of cultural diversity, but everyone in the company is pretty tone-deaf to just how little diversity there is in the organization. But I'm not surprised: it's a pretty monolithic group, so of course, they're comfortable in their cocoon as-is.
