Experience letter related

Sir I filled the form for govt job for wireman. He asked for 3 years in eligibility for the job. I have enough experience as a wireman but in the order letter I got from where I was employed my designation was given as Junior Assistant (Wireman) and in the pay slip my designation was written as Wireman. In the experience certificate my designation was written Wireman. Will this experience be considered valid for getting a job or not??
