IMHO, the term "corporate" is way too broad to be put into context. There's a massive difference between flying for a two-crew owner operation which is a world of its own and flying for a large business jet charter company. Remark: some of those companies provide ops support to aircraft owners, so, while you might have signed a contract with a large charter establishment, you'll only be working on one aircraft with a handful of other people, being confined to this small world of its own.
So, what's the potential problem with flying with the same guy for years on end and not really being subordinate to a large organisation? Standardisation. This environment is the perfect breeding ground for all sorts of informal techniques and practices, just because there's nobody to insist on doing otherwise. And, if you take that a bit too close to heart, you might fall flat on your face the moment you go to an airline where you'll be required to stick to a rigid SOP. My observations are that some corporate guys struggle with that exact aspect of airline flying. Their flying skills may be good, their organisational skills are usually above-average, they often know more about flight planning than any airline guy - but the somewhat lax attitude towards following firmly set procedures often plays a bad joke on them.
