First of all, 28k AED is a very good salary, especially for a bachelor. You will be able to live comfortably and will be able to send some money home. The best part about salaries is that there is no tax deduction here, so all of this would be your in-hand salary. There is just like 5% VAT on the goods and services.
About work culture, Dubai has Sunday to Thursday working, with Friday and Saturday off. Some companies have Saturdays working too.
It is a fast-paced company so the workload can be a little too much at times, so if that’s a problem for you, you can think about it. Otherwise, it is a good place to work, the management is supportive and they have clear roles for everyone. Puffy has some good reviews on glassdoor that you can check out before making your decision.
Personally, I would suggest you go for it. It is a great opportunity and you will get good exposure.
