> An interview is a sales pitch for a product.

While I see your point, I as a candidate am absolutely transparent and honest about anything work-related, be it in the present or past.

To me the relationship employer-employee is very important, I spend more time working for a client/company during the week than I do with family and friends. Thus this time has to be spent in a mutually satisfying and healthy way.

Pitching and selling myself as anything different than I am does nothing but put me in uncomfortable positions.
