  • What are your preferred tools for communication? How have you used these successfully in the past?
  • Tell me about a time where you were working on a software project and ran into problems because of communication. What would you have done differently if given the chance?
  • Describe a time where your team had an application error that was a “fire-drill” emergency situation. How did you and your team work together effectively through that situation? Is there anything you would have done differently if given the chance?

  • If a manager or project leader assigns a task to you, how do you ensure that you understand all of the requirements completely?
