This is how I got hired. The manager talked with me for a while, and then looked me straight in the eye and said: in three years, you need to either be a technical lead or start your own company or you're going to be miserable. If you pick which of those paths you want, we'll help you get there through the work you do here.
So honestly, the question is: would you want to work for a company that wants you to lie to them? or a company that wants you to grow and roots for you when you do?
Clearly you met guys with an awesome attitude toward their potential co-workers.
I doubt most of interviewers who ask the cliche setup* do it because they hope the best for you and are glad they found the perfect match, probably they just brought it from their previous experience with job seeking, or have read them in an average HR manual.

- what was your biggest success in your field?
- what are your weaknesses?
- where do you see yourself in 5 years?
A long time ago a kind of douchebag asked me them while clicking checkboxes on the screen after every answer. Needless to say I had no motivation to even care to go further in the process. A few years later I've heard from girlfriends just after graduation (non-technical field), they got them on every single one of their interviews, mostly asked by HR managers with no particular work experience. The first one is exceptionally funny when the interviewee is a post-grad.
