The door has to be open and there needs to be a friendly face with a smile on the other side. The second major challenge you face is that access to this talent is now a commodity. It used to cost quite a bit of money to run newspaper ads, pay headhunters and have professional recruiters. These things are not going to go way, but have decreased in importance for the entire recruitment and retention process. There's also a mismatch between the structures of the markets.
Labor markets tend to be regionalized and fragmented.
Whereas, the talent market is becoming increasingly integrated and global. Your search for talent now needs to be worldwide and not confined just to your neighborhood. Sourcing of talent needs to be managed as a supply chain process. It needs to be integrated vertically. Increasingly we see the development of narrower and narrower niche talent markets.
