Something very important I have already KASHF kardam (explored), iis that there is a TREMENDOUS difference between these two, believe me:
:

1- I am supposed to do research in Nano/MEMS and.....which brings a sense of working in future
2- I have already worked in Nano/MEMS and etc and will again continue, which bring the sense of having some background in it


If you conditions fall into the first one, the worry could also fall into somewhere around ZERO
