Wiley's data is really duct-taped together, for lack of a better way to describe it. This creates a lot of road blocks from an attribution standpoint and makes it really challenging to have quick turnaround times for campaigns.
Additionally, there is a lot of organizational ambiguity, even after major re-orgs, which makes it hard to get accustomed to having one manager for longer than a few months. This makes it frustrating as an earlier-career employee as it can be really hard to advance. I came into Wiley with a higher title at a previous job, but I was really happy with the mission and the culture. I assumed that over time I'd be able to develop and climb back up to my former, pre-Wiley title. After about two years it was clear it would take me another year or two to get a title change, even after receiving 'excellent' performance reviews and reporting to people 3-5 levels above me (Directors, VPs, etc.).
With all that being said, I think Wiley is the perfect company for people who are a little bit later in their career and not looking to really grow and develop in their career. If you are attracted more to flexibility and stability, then I think Wiley is definitely the place for you. (Although we have gone through about 3 rounds of layoffs in the last two years. I do think things seem to be stabilizing, however.)
Furthermore, Wiley's pay has been far from competitive IMO. Through the re-orgs, many managers are realizing that they make less than their new direct reports who are lower levels, which shines a lot more of a spotlight on a lot of the thoughtlessness with how Wiley compensates their employees. There seem to be many layers of bureaucracy when it comes to increasing someone's salary, but there does not seem to be a lot of structure in how they pay different employees at similar levels.
