I have spent the last week trying to get up to the bank to

  • rder a new card. I looked on the app and it wasn’t there,

  • Can you make decisions quickly?
  • Are you using source control(I know right)?
  • Are you doing Test Driven Development?
  • Does the business understand the risk/reward?
