They would ask you to cite examples and answer the question in STAR format. Situation, task, action and result. Prepare in advance and provide stellar answer to win it, also don't be afraid to ask feedback. Remember that feedback is a gift and it will help you on your next application in case you didn't land a job offer.

Applied directly to the Company. Had a one hour and twenty five minute interview. Nice people, enough questions to me to make me think there was interest in me. Slightly confusing as they enquired as to what role I was there interviewing for (there was two roles - though clear which one I applied for on their website). Have not heard back from them with any feedback, though I left the manager who contacted me directly a voicemail and a message with HR to give me any feedback. Ongoing, no feedback for nearly fourteen months.
