Will bank give me a loan if I've only been working at new job for a month?

There is only one way to find out, isn't there? You need to apply. They will take into account your previous loan history, how long you've been working at your current job and how long you've worked at earlier jobs - plus how long you've lived at your current address. What emphasis they put on each (all signs of stability) I have no idea.

You have bad money habits. Consider buying a book by Dave Ramsey. I used to have to get loans when something unexpected came up but once I paid them all off and have a nice savings account I no longer waste money on interest. I pay as I go.

They should, you should give it a try, ive never heard of the bank rejecting someone who has been working at their job for a month.

Save your money and pay cash. When you borrow money you are in servitude to the bank until the debt with interest is paid. There is an old saying; "Neither a lender or bowworer be"!
