Job Offer Dilemma: Should I Resign Without a Signed Offer Letter in Hand?

I have received a job offer from a reputed company in Muscat based on my professional experience. I have already signed the offer, and the surprising thing is that the GM is unwilling to provide me with a copy of the offer letter. He has committed to giving me the contract and offer letter duly signed by him on the day I start my duties. I now need to submit my resignation to my current company, assuming that I will secure the job with this new company with its attractive offers and facilities.

When I inquired with the GM, he explained to me that it is company policy not to issue hard copies of job offers due to confidentiality reasons. He assured me of a better position under him as the Operations Manager, as stated in the offer letter.

Please advise.

How is the reputation of the company? Try to gather information about the company's hiring policies from its current or former employees. If you receive satisfactory information, then you may consider accepting the job.
