I had an offer from Cadence few years ago which I turned down, then, for personal and career development reasons. The circumstances changed since then. Contacted by interested manager through familiar recruiter. Lunch with said manager, followed by a formal interview with hiring manager and senior architects. Normal, old-school previous experience and technical ability interview. No "solve me a puzzle" nonsense for the experienced with good known references, even though I was prepared (get a good book and be prepared!). Don't know how recent graduates are interviewed.
