On average most firms will create a credit profile based on your work history, your income and also your education. While changing works should not be a show stopper, certain firms expect at least 6 months of constant work in order to approve loans. In most cases, you can explain the situation, prove that it is a new job, a better wage or anything related to making your case. At the end of the day, it is going to depend directly on the person reviewing your application for them to determine if it is important for your application.
