This question already has an answer here:
I got a conditional job offer (pending background check).
My resume stated I worked for a company from Sept 2007 - Jan 2010. But, I worked for them from Sept 2007 - April 2009, and from Sept 2009 to Jan 2010. I decided to leave (quit my job) and travel. After 4 months and getting back, they again hired me in the same position.
On my references of each company, I gave them phone number of the Director (company's number with extension), but during background check they called the HR dept. and that's where the discrepancy happened.
I have been told that they are unable to verify my employment on those 4 months and is asking me proof.
The company uses 3rd party for Background check and I spoke with them and they only verify employment record by talking to HR and won't accept anything else.
Any advise how to tackle this issue?
Edit: I have looked at the following question, and it doesn't address my problem: Issue with background-check on previous employment start-date
