No dear,......different locations doesn't mean different jobs. My case is similar and I've worked in different cities for the same company doing the same job over the country.....So don't worry,....all is fine until the company is issuing the letter confirming your stint and job responsibilities.As part of my work history? Because that would technically mean different jobs and would require separate experience letters to substantiate. That's not the case here: it's the same job with the same company and in the same country..just cities are separate. The experience letter I have covers my entire stint in one go (as it should be).
