Um, possibly. That's not much of an employment history. So it brings up a few questions:

Did you get the new job after leaving an old one (without much 'down' time between gigs)? If so, then you have an employment history that goes longer than 4 months.

If this is your first job, 4 months is not a lot of time. Is this a job you expect to hold for a long-ish time, or is it biding you over until you get something else? Are you sure you need to get a car loan? Taking on a loan without a steady full-time job is kinda dangerous to your wealth. Have you worked out a budget for your life or lifestyle? If not, there are plenty of tools online to develop a budget to determine what you can reasonably afford. I've even got a half-baked one you can have.
