It is what sold me. If a search firm internal interviewing process is poor, outdated or lacks credibility, how will they be any stronger when interviewing candidates for their clients. My interview was all about me, without them pitching their opportunity. They wanted to know how I grew up, under what value systems, who was my role model and why, etc. They searched for my work DNA and only then did they tell me about their job when they knew I was right for it.
