“he’s in a meeting”

Nup, him and his dickhead recruiter mates are all having a circle jerk over a mirror in the boardroom. Sometimes they let the realestate agents from next door join in. Its the only way either of 'em ever get any love.

It could be reasonable that they are sometimes on calls, eg interviews reference checks, client calls etc, but I reckon not returning your call twice is probably a sign. The right thing will come along.
