Caginess and dodginess in this answer is a flag. Of course, different interviewers will be more or less forthcoming and straight with you, but if the entire slate of interviewers hem and haw around the question, I take it as a bad sign.
An organization where people are afraid to be frank and call a spade a spade is hiding a lot of systemic problems.
(although now it's been on HN interviewers will probably be better prepared)
Every company/organization/person should have a long term strategy. That way you can weigh potential actions to see if they are moving you toward or away from your goal. If you don't have that goal, or it isn't well communicated, everyone scrambles to optimize for different things, which frequently leads to people pulling against each other.
It's totally acceptable to update the long term goal as you go along, but it's very helpful to always keep one in focus.
