It is more than likely that Airbus will have you sign a non-compete form in your role at the organization, as they work with confidential and privileged information. The interviewer would like to avoid any hurdles during the offer and negotiations stage that would prevent you from being successfully onboarded. If Airbus is a direct competitor to your current or most recent employer, then you should carefully review your employment contract to ensure nothing is hindering you. Be prepared to present the agreement in your late-stage interview.
