I worked at Nova and I have a Master's degree (quite rare, as noted above.) I was actually paid a little more just because of my Master's. If you have one, tell them.

There is a danger of being "over-qualified" at Nova. Do not be waving around a bunch of high-falootin' theory in your interview. That is exactly the kind of thing they do not want to hear. We had one lady in our training class who had taught at the college level in Japan, and she brought a lot of her "own stuff" into the classes. She did not survive training.... The main thing is, just stick to the text, and do not get fancy.

Age: Not me, but they hired one fellow at age 65.
