I applied in-person. The process took 1 day. I interviewed at Currys (Londres, Angleterre) in Oct 2014
Interview
Brief discussion on soft skills and trying to establish a suitable role in store. Was then called back a second interview for a further discussion. The process was very quick and recruiters were friendly.
Very easy and relaxed, I was there for 10 min, basic questions were asked. Wear a suit for a good impression. Make sure you read up on tech they have there and have a good idea of what sections withing PC world you would want to work in!
