Dated info, but there was at one time a policy that anyone that went longer than year from interview (or CJO?) to actually on property had to go through a "re-interview".

Granted, NOT a full on actual interview. But a face to face and just review/update personal info to make sure nothing changed, you didn't turn into an ax murderer or have anything criminal/disqualifying added to your record, training failures/dings, etc.

Again, dated info.
