Moves quickly most days. Long line ups to get through, most of the time working through lunch breaks.
Does Tom Harris Cellular allow for flexible working hours? Or are the hours set?
They can be flexible. It is a retail environment so you need to understand that when applying for the job. Don't expect to have time off (like a vacation) during the Holiday season.
Bring enthusiasm and "oomph" to the interview. Be a go-getter. Take the time to learn what makes a good salesperson before you go so that you can demonstrate a willingness to learn how to do that if you don't have the skills already. They're very customer-service oriented. Look up their website and their vision, check out what they do on social media.
