2 Interviews, 1 initial interview to assess capabilities, the second was a task based interview. First interview was nice, very friendly. Recruiter actually sent me the wrong day but Keystone were kind enough to interview me anyway. I was then invited back for a second interview and had to prepare a presentation and present to a panel of 3. It went OK, I was quite nervous, however, created a good presentation. Unfortunately I was not hired, and did not receive feedback as to why - after taking 2 days out of my current job to attend, I think it was bad manners from the Keystone company to not at least offer feedback. I saw they advertised the job a further 2 times in the following 4 months. It seems they should have really offered candidates feedback and allowed for nerves as interviews don't always show a true reflection. They may have been overly picky, considering they were re-advertising in July, and I applied in January.
