Pros
Compensation is fair as far as I can tell, and the benefits are good. They are flexible with accommodating various life circumstances. The Hoboken office is nice, and looks out on a lovely park built right over the Hudson River. People are polite and civil - this is one of the first things I noticed about the company, and it's still appreciated - everyone is "Wiley nice." Manners are good, and there aren't many a**holes to be tolerated, at least among employees - there are still ill-tempered people among external authors and editors. It's a fairly civilized, comfortable work environment.
Cons
Your experience there is all about your manager - if your manager is looking out for you, everything is good. If he's not, or if he's more concerned with kissing up to the people above him that taking care of his team, as in my experience, you can stagnate. Also, a lot of their rhetoric about Wiley being "the place to be" is just talk. In practice, you're a cog until you're not, and working your way up can be painfully slow. There is also a tendency in my group - don't know how this applies to others - to over-manage competent people who don't need it.
