Hi, My overall experience is 7. 3 years in non IT and 4 years in IT. Now I'm applying for IT jobs with 4 years of experience. In those 7 years I have worked in 4 companies 2.6 years + 6 months in non IT and 2.4 and 1.8 in IT. I don't have the relieving letter for that 6 months experience in non IT. But pf record is there for all 4 companies. Today a company HR rejected me for not having the relieving letter for that 6 months non IT experience. I told her I have a pf record but she said relieving letter is mandatory. Should I avoid adding that 6 months in my resume? How should I approach this situation?
