I adopted mine at 12 months old and he was terrified of everyone. I cannot vouch for his upbringing since I never met his previous owners (breeders) in person, I can't begin to guess how much or how little interaction he had with people. The only thin I know, is he was scared and not playful. It took him 3 months to be comfortable with me. I doubt that's the case with your pup, but you can't expect an instant bond either. My pup is extremely playful, and walks around with his little tennis balls in his mouth, always ready for a game of fetch.
