Please share the names of TWCG and HPC so we can all be sure to avoid them ourselves.
2nd that. Though if I were a betting man, I'd place wagers that HPC is a company in the Northwest, or goes by the moniker that denotes an EXTREMELY large number.
On the issue of unprofessionalism, TWCG is pretty bad, and the HR Drone at HPC listening in on your conversation without your knowledge and consent is unacceptable.
