I've only been with easy a few months so i think the interview format is still the same.
There's an introduction from the recruitment team and an intro to the company.
You then stand up and introduce yourself.
They project a list of about 15 questions and you have to go round the room and ask each other the questions, then stand up and tell the group the answers you gained.
You then have to build a bridge in groups from paper and paper clips.
Then you complete questions on the company and a maths test.
You then wait while the test are marked.
Next you go through to a one to one provided you've past your maths!
Good luck!!!!
