Mine took less than 3 minutes.............I was asked the knida phone i used and i answer N72 so he asked me to market the phone to him, i started by telling him that i browse on ma phone and it saved me cost it its convenience to pass information to lower staff at office also i mention application that makes the phone unique and good for him to buy.
He stopped me as i talked so i left only to be invited for a second and final interview barely 24 hours after. Good luck
