I don’t know about this particular situation but I think it’s just a matter of politeness that somebody new should use his first weeks to try to understand the current situation before making too many suggestions. Also show your skills by delivering something.
I have seen quite a few contractors who didn’t seem to be able to do anything if the environment was not exactly their preferred environment. If you are good you can deliver something in any environment and build up credibility.
It's partly that yeah, in my case the issue is that what they called skills were just hardship turned into experience which didn't call for their propensity to insult / accuse me (behavior that they rarely did between themselves).
Basically it's clan mentality that makes it hard to integrate because they don't transfer knowledge or confidence but authority and rot learning procedures.
