I’ve completed this application form on two separate occasions, weeks apart. Both times I tried completing the form in Firefox AND Internet Explorer. Spent hours perfecting my answers.
As of yet, I’ve been unable to successfully submit the application form due to technical glitches. Totally put me off the scheme.
EDIT - I’d like to add that their graduate support is terrible. I spent 30 minutes being passed around numerous call centres trying to find a number for their “graduate team”, but in the end was told that they had no direct number. Sent them an e-mail weeks ago, still not received a reply. From what I’ve heard, a lot of graduates have had similar issues.
DOUBLE EDIT - I appreciate this isn’t the answer to your question, but I think it’s fair to share my experience. If you manage to get thorough the shoddy application system and submit your application, let us know how it goes!
