I know both totally honest and trustworthy sales people. I also know others that seem trustworthy but actually don't know what they are talking about, lie constantly, yet so far after 10+ years in their respective careers somehow manage to get very far ahead of the game. You may say they are simply effective self-promoters and I should not be envious, but I disagree. If you don't believe in a product, it is wrong to tell others it is great. If you have no idea how to do something, sure, say "No problem, I'll get right on it", but it is wrong to say "I have done that tons of times". With products it is fairly easy to see what the truth is: An advertisement for a product may say it is magical. A reviewer may agree. You try it yourself and find whether it is true or not, for you. With people in the workforce though, especially in fields where the cause of a particular team's success or failure is quite difficult to quantify, detecting the bullshit artist from the solid player can be extremely difficult.
