Is it ethical to omit the PhD credential from my resume? I am applying for a Statistical Programmer position at a commercial research organization (CRO), and I am wondering if it is unethical to omit my PhD in Statistics from my resume?

All of my degrees (Bachelor's, Master's, PhD) are in Statistics, and I am just wondering if it would be ethical to just list my Bachelor's and Master's degree on my resume, and indicate my experience as a RA while I was a PhD student as my "work experience"? (Since this Statistical Programmer position only requires Master's degree plus some years of experience)

I am asking this question because I do not want to do anything unethical/cause me troubles later on.
Do you think that such a deception will help you significantly in landing the job? Several years of “work experience” at a university is going to look very suspicious and will probably raise some flags.

In general, you’re always better off stating the truth. There’s a smaller chance of things going sideways down the road if you do.
