Cadence was perhaps the least satisfying company I've worked for over the past 20 years.
Pros
The coworkers were enjoyable and mostly good natured. The payscale was quite good even though there were frequently pay/hiring freezes and no bonuses.
Cons
As a very senior software engineer, we were supplied with very old, slow and inadequate computers and ancient code. Getting a second monitor was considered a luxury. There's an old-guard, don't change anything mentality where presenting new ideas many time is considered disruptive. Vacations/Shutdowns are strictly enforced during specific times of the year, and new employees were required to borrow against future years. Design/development process is rigid, non-agile and counter productive. Layers of specification approvals were required before any work or prototyping could begin. As a developer, the spec reviews were over attended, sometimes contentious and provided little assurance that you would be developing what was actually required since the attendees almost never came prepared (well, in the 6 years I was there I never had one where everyone who "just had to attend" was prepared).
