Infosec is still pretty hot in terms of hiring. Companies only spend the money they have to on security, so they haven't really been able to cut it at all unless they're accepting higher risk (which some are, but the skill gap is still huge)

What role is he going for the he can't get interviews? My LinkedIn inbox is still consistently full, and I have had no problem getting interviews when I poke around to test the waters

For anyone with experience, most technical security roles are plentiful
