Much better written article
I've just sat through interviews (and managed to get myself a new job along the way), and sticking to this kind of advice got me through. The technical questions myself and a number of people I know sailed through - it was the examples, honesty (about my limits) and being able to chat to the managers got me the second interview, and eventually the job.
And what surprised me most? I got this through a recruiter who took time to talk me through the role, gave me hints, a lot of prep (sheets of potential questions to try) and useful feedback after the first interview. And even agreed to go back and negotiate more money than I'd originally asked for when applying when they offered the role. Unsurprisingly, I'll happily use him again if I need to look for a new role.
