career-holed
To choose a college major or enroll in a training program for a job field or profession that is desperate for applicants and is hiring like crazy but by the time you complete your education/training the market for your skill has become saturated and nobody is hiring.
Before I enrolled in college there was a shortage of electrical engineers,they were hiring like crazy and making top dollar.Four years later I have my degree but all the jobs have been filled.I just got career-holed .
