The "contacting recruiter" podcast was excellent as is so many of the others that Manager Tools (Mark & Mike) have put together.
In the podcast you mention having / maintaining a relationship with more than one recruiter. I can speak from personal experience as to the importance of your recommendation.
In the past I worked with one recruiter for my last two jobs. Unfortunately, I failed to maintain contact with this recruiter, and failed to cultivate a relationship with an additional recruiter. This recruiter has since left the business.
I have begun developing a relationship with another recruiter (as per Manager Tools) whom I was referred to by a colleague in my industry.
I don’t want to put “all my eggs in one basket”.
As I pursue cultivating a relationship with an additional recruiter should I tell him / her that I have begun working with the 1st recruiter and vice versa?
