I think you can began evaluating whether it's a 'dead-end' job long before the interview, potentially saving both you and the interviewer time. 1. Search LinkedIn for current/former employees of the company who held the title you are evaluating. How long did they stay with the company? What were they up to previously; what are they doing now? Were they able to grow their responsibilities/title at the company? From what you can tell, do they sound like someone you would learn from or want to work with? 2. Glassdoor. Sort reviews by date, then filter by those specific to your department. 3. Speak with a few recruiters. Ask them about the company you're considering.
