Postal OIG

[FutureAgent001]

I searched the forums but was unable to find any threads on USPS OIG since 2008. I'm a current 1811 with another agency who got the call for the interview. Is anyone currently with USPS OIG willing to provide any info about the position? I'm curious about quality of life, caseload, travel, and job satisfaction. I saw on their website that they made over 1000 arrests last year for a variety of cases. That's very active for an OIG. Also, the announcement I applied to listed it as a GS 11 at the journeyman level....I've never heard of an 1811 not going to at least a 12. Is there any opportunity to move to a 12 or 13 non competitively? Thanks for any guidance.
