Questions, questions, questions.
I'm currently reading "Who: The A Method for Hiring", by Geoff Smart and Randy Street. It's a book about how to go about hiring top quality people and it's a real eye-opener for me. I'm only about half way through, but I've learned a lot.
Reflecting on what i've already read, there's a lot in it where you could say "That's obvious," but I don't think that that's the case upon deeper reflection. It's really about clearly understanding the role of recruitment (and the role you're recruiting for) and putting together a proper 'hit list', or business plan, almost, in order to get the best people in front of you. Then comes the 'Topgrading' interview and, finally, when you have identified the person you want, sell the job to them.
Throughout the text it's very evident that questions are at the key to all stages. Particularly in the interview, keep questioning, questioning, questioning until you get to the heart of the person. But also question yourself - the mission for the person in the role, the skills required, and the goals they'll need to meet for you to be confident in your selection.
As a manager, I'm finding the whole book to be a refreshing perspective on the recruitment process. However, I would recommend anyone who is looking for a job to have read this book because, whether or not the person you're sat in front of has also read it or not, you'll be in a far better position to present yourself, your skills and your potential to the interviewer far better than the other candidates.
