It all depends on the nature of the private job you are doing because if the private job is very lucrative and it's related to your area specialisation I don't think there's any big deal looking for government job you can build your career and become an hot cake in your field.I have always considered private job as a temporary job that you can do while still searching for government work because it is not actually the best for you to work for private individual ,is either you work for the government to me or you establish your own business.
