Application made online, 3 weeks later received a phone call invite to an interview. Interview took place in London office and lasted an hour & a half (informal, with 5 "formal" questions). Took several weeks and a few chasing emails to find out whether I had been successful or not. I wasn't, so asked for feedback as I felt it went quite well & haven't heard back. Overall process took around 8 weeks.

Invited to interview in Leeds, was told a week prior to interview to prepare a presentation on a case study. I spent hours preparing this presentation and researching the case study- baring in mind that is was a couple of weeks before my final year dissertation was due in at uni. The interview was very casual, more of a conversation with no set questions. Then at the end they said "shall we have a quick look at the presentation then". They gave me very positive feedback and told me it would be 2 weeks till i heard back. 1 month later i received an email saying i would hear the decision a week after. Its now 3 months later so i assume i was unsuccessful. I think its completely unprofessional and rude to not bother with a quick phone call or email to let candidates know the decision after its clear that people spend a lot of time preparing for it.
