Alphabet soup agencies dealing with datamining and hacking routinely go outside the normal loop for hiring. t's not abnormal for someone to be hired into a placeholder position such as a custodian and then moved into what they were really hired to do when their security clearances come through.
One of my friends growing up was a junior high dropout, hired by DEC as a security consultant at 14 years old.
