Tweaking some parts of your resume is not technically considered to be illegal. Your resume is not a legal document, so usually, there is no scope of inviting prosecution charges for lying in your resume. But during an interview, if the interviewer finds that your skills do not match with what you have mentioned in your resume, that can potentially land you in trouble – you might get rejected for the job offer. So ideally, it is safest to not lie in your resume and blow facts out of proportion. However, if you falsify papers meant to support your educational qualifications, that could invite legal problems.
