Pros
Dell benefits. The list pretty much ends there. A lot of the pros are now either gone or going away.
Cons
They are frequently changing direction. This isn't because something better comes up; it's because they don't know what they're doing or what the real value is in the technologies they produce and then abandon. Re-orgs are so common that within a year your team name can change, your mission can change, and your manager can change twice (or more). I had a whole paragraph written about their frequently changing priorities, but it may give away too much corporate info. Let's just say they've changed their mind three times and abandoned some platforms, and now they're going in a TOTALLY new direction that makes no sense. Who knows where they'll be a year from now. Their most talented, senior-level experienced engineers can't leave fast enough, and they're doing little to try and 1) figure out why, 2) keep them, or 3) replace them. Instead, they're backfilling those spots with non-US engineers. Above the first layer of management, promotions aren't exactly happening based on merit, so the technology direction of the company keeps moving in the wrong direction. They've expressed their desire to split DevOps into Dev and Ops units, and honestly have no idea what DevOps or SRE roles do. NONE. The company's culture is going the wrong way, and looks more and more like a tech company from 10 years ago. The only saving grace is that Virtustream is under the Dell umbrella. Other Dell companies are not like this, and it's easier to move to one of those companies once you're in Virtustream.
