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.
