I took a contract once at a mobile handset mfgr that had this. This sysadmin-cum-manager dude (with zero previous management exp) thought he was hot sh*t because of his title. Dude was robotic/patronizing fake, arrogant, useless, and just got in the way. He thought his role was to unsolicited "coach" mission statement BS and insult my intelligence.

Oddly enough, I was fired from that gig for witnessing a senior manager repeatedly mute the conference call to make racist remarks about overseas staff.
