I have been in sales for over 10 years now and have many years experience in a high pressure sales environment and i think that hold me in good stead when working in a sales role also all of my working life my jobs have customer faced work in different roles.
working as a barber is very personal job or the customer and a lot of trust is put on you from the client ,it is a little different with sales but both need trust from the customer in you. My later work in sales has been in a team role so i have had to adapt the way i approach the role in sale as you have work with you team and management as well
