I'm a 25, with "auto" experience. I selected the default recommended nations. I start the game unemployed. I applied for all available vacancies as manager. However, all of them were rejected. So, how do you actually get a job starting unemployed?
If you select "auto" rep, your reputation is automatically set so that you can only get a job in the lowest rep division you have loaded up. Do what khemo said, holiday indefinitely you should be offered a job by January as lower division clubs are always sacking their bosses
Going unemployed is what I mostly do now, adds to the realism and I find it much more of a challenge to take over a struggling club outside of the transfer window. Saves all the rigmaroll of pre-season as well.
