I've just done 5 loads of interviews for the civil service so have interviewed over 50 people this last month. All for EO roles.
Best advice is be prepared, print off the answers you sent in your application form, you can use these for the behaviours. The questions will be on your behaviours.
It should tell which ones in the advert.
Don't take more than 10 or so mins to each question. When they stop writing STOP TALKING.
Be prepared to be asked why you want the job or what attracted you to it.
Don't for the love of god say "Because I'm unemployed and need a job" had 2 people say that!
Understand what the department does and google to see if there is any further info on it. Any news, new initiatives? .
We know you're nervous, we want you to do your best in the interview.
Have a glass of water beside you and take sips of water to calm yourself or give yourself time to think.
If you don't understand the question ask them to repeat it ( it will be one of the nah hours).
Dress smart. If you can put a background on so we can't see your messy bedroom :)
But this can make it difficult to see your ID. Talking of which have your ID close at hand. Had a couple have to leave to get their driving licenses.
Write out bullet points of things you want them to know about you. Or you feel are important to say.
Ask a couple of questions at the end. What is a typical day like? Why do you enjoy your job? What do you think is the biggest challenge with this roll at the moment.
And SMILE! Keep smiling. They're lucky to get you. It's a two way street, do you think you could work for these people?
If you don't get through ask for feedback.
Feel free to ask me any questions :)
