In January 2016, I interviewed with a very large company for which I'd very excited about working. After 3 weeks, they interviewed me again and everything looked good. After another 3 weeks, they called me and told me they preparing the papers and I got the job. Then they got quiet.
After not hearing anything from them for almost 6 weeks, I followed up. They informed me that I will start with them in July, and I should start planning, as this job include relocation back to my home country. However, this was still only a verbal offer without a written job offer.
Ten days ago, I sent an email and called as they previously told me they hoped to finalize the offer last week. I asked when to expect an official job offer and there has been no response to date.
I have another offer in hand, but it is not really something that excites me.
How should I handle this? Should I resign my current position? Should I continue waiting on this position? Should I accept the other offer and move on?
