I finally managed to try out Google Instant (I thought it wasn't enabled yet, turns out it was. It was just not supported on Firefox.. or perhaps a certain FF plugin prevented it from functioning.. worked for me on Chrome, Safari and IE8).
I've been interviewing people for the past five months and it has been a very insightful experience for me. I had to analyze what was required from the new recruits in terms of technical competencies, I had to come up probing questions that really showed their true capabilities as well as their personal characteristics.
