I am doing full time PhD and receive scholarship from university. I want to add that as a work experience. What job title will be appreciate for making resume for industry job?
Put PhD Candidate. Contrary to what others suggest here IMHO it is not lying to put it under work experience (where I am from it is considered a job and you get the normal job benefits).
It might depend on the rest of your resume and the exact job you are applying for whether it is better to put it under education or work experience. I have gone both ways in the past (on separate occasions ofcourse)
Your job title needs to reflect the actual work performed. Being a PhD Candidate may be hard work, but your education belongs under the "Education" section of your resume.
Typically a PhD candidate is performing actual research of some form within their chosen field. If you are a research assistant, you use that and you describe the nature of the work you performed, your responsibilities, achievements, and so forth within the normal format for "work experience".
Your status as a PhD candidate goes under education, along with any other graduate or undergraduate degrees you've earned. You may also want to list where you are in the PhD process.
