What is your greatest professional achievement?
"Try not to go too far back and pick a recent achievement which will relate to the role you are interviewing for.
You can tell a story about a big project that you led. Start by talking about why the project was necessary and what the challenges were. Finally, you want to talk about how the project was finalised and the results of it. Make sure you show ability to work in a team and most importantly, pick a project that was a great success, of course!"
