I just finished my call with the HR Manager. After bringing up the flight and hotel costs, she stated that the offer was going to stay the way it is and they were not offering me anything additional. She expressed her "concerns" about this international move possibly being a financial burden for me, at least for the first few months, given the higher cost of living among other reasons. I have until Monday night PST to give them a definite answer, but from this call I'm feeling like maybe this is not the right opportunity for me at this time.
While I am definitely appreciative for this amazing opportunity, given my age and work experience, the fact that the Director of Marketing stated that I would indeed have relocation assistance and now is refusing to offer it makes me question the company's motive for even wanting to hire me.
In any case thank you to everyone who offered their opinions and insight on this matter. Each response is greatly appreciated.
