Must maintain full-time status to maintain TA status. There were no interview questions, I was hired solely because of my status as grad student and 2+ years of nursing experience. Because of the lax requirements for becoming a TA, many graduate teaching assistants were severely unfit for their teaching roles.
There was no formal interview, I was a grad student and I got the job automatically. They did give us a lecture on proper teaching assistant behavior (ie: don't take bribes for giving higher grades, etc...) but it was all common sense stuff and easy to adhere to.
The role of teaching assistant is more challenging , varied and meaningful than anything I have done before. I want to work in a field where I can make a real difference to people's lives and witness the positive impact of my work first hand. Less
