Generally, you only apply for a credit card if you need cash flow in the short term. Why would you apply for a credit card when your job is not stable? Credit cards have to be repaid. Before applying for a card, ask yourself if you can afford it? Overdraft of a credit card above a certain amount will result in criminal liability. If your job is stable in the short term, and if you are in urgent need of cash flow, there should be no problem if you can provide proof of employment.
