Have you heard of "Ghost Jobs?"
No, it's not when you get hired to be a ghost, these ghost jobs are essentially not real jobs. These jobs don't really exist. Companies post jobs with little or no intention to fill them. They are using these postings to gauge the talent pool.
So how do you avoid applying for a ghost job?
CHECK THE JOB POSTING DATE. Jobs that have been posted for a longer time have a higher potential of being a ghost job.
