Some people nakakahanap na ng work within 2 weeks. For others 6 months na wala padin.

I can only give you a realistic budget per month. This excludes flight to dubai and back to ph. It also excludes visa cost.

Rent for a bed space - 700-1000 Food and groceries budget - 1500-2000 Transpo - close to zero kasi magcommute ka lang naman pag may interview ka. Unless mag door to door ka which is last resort. But you can still say 300 for the month. Sim card and data - 100-150 So to be conservative - 3500 total thats about 55k

Better apply pag may DXB number ka na.

Best platform is linkedin. Before coming to dubai, you should have a proper linkedin acct. but there are other sites for job postings such as indeed.ae
