Esther Schindler has a post about in­ter­view­ing your next boss: should a candidate dev manager meet everyone who'll be reporting to them?

Yes. Definitely. If you want a successful, cohesive team, there has to be trust. A manager can make or break a team.

A new manager starts at a dis­ad­van­tage, relative to a new individual con­trib­u­tor. The new dev is expected to ramp up and have time to build re­la­tion­ships with the team. The new manager has to build the re­la­tion­ships as soon as possible.

If the manager gets to interview with the team before being offered the job, both parties benefit. Why would you want to manage a team that you'd never …continue.
