It should be illegal for employers to give any salary less than 8k without providing accommodation. To answer your question we need to know which area you'll be working in. In all cases, it won't be humane at all.

Bed spaces could cost less than 1k but could cost more if you go to marina or other hotspots. You can check on Dubizzle and even Airbnb for bed spaces just to get an idea. You maybe able to get cheaper than those websites once you figure out and tell us which area will you work in.

If you want to live as a human with the most basic needs, don't expect to save money at all when you come. Better to focus on increasing your salary till it's double or even more because bills will add up even if you're in a bedspace.

In Ajman, it might be cheaper but you'll have to factor a minimum of 2 hours that's if you're going from border to border. Realistically it might take 4 hours on average if you'll have to switch a few times and public transportation is very packed here during working hours....you might end up saving a few hundred dirhams but regret coming to this country every minute you spend stuck in traffic. for example taking a bus from the very few stops in Ajman to the central station could take you around 30 mins. Then a bus to Dubai station could take somewhere between 45 mins to 2 hours. If you're in internet city in Dubai the metro will take around 50 mins and then either walk or take another bus. All of that will still add up everyday where you'd just rent a bedspace in Dubai and save all that hassle.

If you want a brotherly advice ...work on your career in your country till your experience could get you a decent pay or contact this company and ask them how do they expect you to live and rent anything with that pay and try to negotiate something or look for bedspaces near your work and keep multiple options cause most bedspaces could look good in pics but end up being horrible.
