Metrics are irrelevant. Anyone can memorize a number.
Print them out and understand them. Gain an understanding of how to impact them. Speak to your leadership and how you will use that to drive your team to improve. YOU can't impact anything alone, and the bulk of the metrics will be influenced by your team and their direct behaviors. Being able to speak to how you will direct that will be infinitely more valued than just knowing metrics.
Leadership Things you can speak to:
-Communication: Tailoring how you communicate to each tm to help them better understand your expectations. Be fluid in your communication style, everyone responds to different methods.
-Confidence: Not being afraid to be the one to make unpopular decisions. If you're confident it's the right call, make it.
-Accountability: its key, in all things. Both your team and yourself.
-Lead by example is a sham. Lead by respect. If you train your team well, communicate, and take care of them, then they will go to bat for you.
-Time management: specifically knowing when to be hands on, and when to delegate. There is a time for both. Realists always accomplish the most.
-Help is never a bad thing: don't be afraid to ask for help. Reach out to peers, learn from experienced people who work for you. Find out what works and what doesn't. The people who do the work day in and day out often have the best suggestions for improvement, give them a voice.
-Always be on the lookout for people who are hungry to learn. Just because someone isn't s great leadership candidate doesn't mean they can't be a very strong asset. In everything you do, teach.
If you can speak to these things, and more importantly execute them, you'll get the job and be successful.
