Are you hiding something in your resume (CV)? I read a lot of resumes and I can always tell when someone is hiding something or "stretching" the truth a little bit.
Don't be so cryptic with your resume (CV), just explain where you worked and what you did there. And, of course, your education and any accomplishments (awards), etc. That's it!
Don't stretch the truth or lie on your resume (CV), the days of getting away with little white lies on your resume are over.
Good luck to you!
