Bang and WOW
The first 3 minutes and the last 5 minutes are your critical times for advancing the sale.
Start with a bang and end with a WOW.
Starting with a bang will entice the potential client to listen better.
Ending with a WOW will make you memorable after you leave.
If you don’t get hired at that time, you will stand out as more than a commodity purveyor and get lost in the mob.
