If I read this correctly, the main negative point was that the author was not paid as much as his colleagues, though he did get the position. The author suggests this is because of his height. To me (a young professional in the software development industry) that screams that the author did not know his own worth and therefore did not negotiate a high enough pay. I'm young for the positions I have held, and am roughly of average height, but you can be sure that I will get paid the same or more than my colleagues, because I understand how much I am worth and I am willing to say as much.
