OP didn't say anyone from his cohort is actually unemployed. The job at Trader Joes may not be what that person was envisioning, but it is a job.
Even if they claim something more specific than literally any job at all, they'll probably count anyone doing something related to IT (if only for a week).
I've also read about boot camps hiring their alumni as teachers/tutors for a bit if they can't find a job. I always assumed that's mostly to be able to count those people as successfully placed.
