If the phone was reset correctly by the store who sold you the phone, the iPhone 8 would have powered on to the "hello" screen. You would not be asked to enter a passcode at this time.
If the phone did not display "hello", the phone was not reset correctly by the store.
Return the phone and make sure that the replacement powers on to the screen that you see above.
Did he type in the passcode correctly? Or is the iPhone locked asking the passcode of the previous owner? In this case you need to contact the seller and ask to delete the iPhone from his account
