Salesman

This is my fifth year in USA. I am still trying hard to cope up with my new life. The latest buzz is about the job. I am on the verge of my graduation, I need to find a job. So I am trying to prepare myself for the job market. Well, I am not sure why I need to know why I need to know how to sell myself, I am not applying for the salesman position. I am applying for engineering position where I would make things not sell things. I need to know how to makes things right so that they are sellable. But sale is last thing I would do, yet I have to fight with my salesman skill to find a job. Is not it funny?
