"Cabin crew have to go through safety training every year. But it's more than just once a year. Before each flight, they're questioned on procedures to make sure they know exactly what to do should they need to put their training into practice." All that training begins in the rig, Virgin Atlantic's training facility. Share any prior experience you've had in this regard. But more importantly, emphasize the value you placed on that training, what you learned and retained from it, and how you put it into practice every day. Assure the interviewer that you possess the emotional intelligence to remain calm and confident in your ability to handle an emergency situation in a professional manner. If you are new to the industry and do not have the related training, be honest about that and comment on any other training you've completed which could be relevant or helpful.
