I've worked for many organizations of different types during my long, perhaps not-so-illustrious professional career: software and business shops; Fortune 500 and VC-funded startups; in retail, financial, healthcare, hardware; bleeding-edge and technology laggards; as employee and contractor.
And despite the experience, despite the many interviews, the job reality is often different than the interview reality and what I thought I learned. Probably you'll never completely know without contact with recent experience working for the employer. Job boards are often a mix of mad ex-employees and frustrated current employees, while HR attempts to tell a more rosy story.
