You did not count all the jobs that get put up and taken down after they filled. When times were good my old company used to advertise for positions they had plenty of... didn't "need"... to keep the door open for any really great guys who become available but that's how you make a company better.
Anyway with the market crashing and virus spreading won't have to worry about too many jobs for a while (where's that sideways-smile face guy) glad i'm retired.
