I also think making cold calls is in itself unprofessional. It shows that you are not bothering to take any interest in the client or the company that he/she is working for. You are simply screwing them for business. I receive about 5 calls a day, most of which I take or I ask if I am busy to call back later, so I know the feeling.
Nor is the art of communicating and networking all about calling every 3 months. The communication should be that you are usually giving something to the client, and that something must be of value, whether it is a link to a local lap dancing club or it is information that relates to his/her company and/or his job. By giving something first it is easier to then get back information than it would be by simply firing off 20 questions.
There is only one reason why clients are not responding to you and that reason is you and only you.
Boy - this thread evolved...
First off, Jill, thank you for using a provocative title for your thread. Without it, we wouldn't have all this quality feedback to ponder over as we consider how to do our jobs better and, in turn, add value to our candidates and clients.
Second, maybe this thread has hit on something. Jill was able to garner some outstanding feedback by using a different, risky, and creative thread title. This may not have been her intention, but the results have been outstanding. Is there a way to take this lesson and use it to gain the attention of hard-to-reach hiring managers?
Third, if you have a long-standing relationship with a hiring authority and they don't return your call or email in a timely manner, that is RUDE and UNPROFESSIONAL!
Fourth, it is funny that 10 years ago everybody thought the internet and technology would revolutionize business. In some ways it did. In others, such as personal interaction, selling, and, in our case, recruiting, it has only amplified the problems sales people faced 20 years ago. As a result, knowing how to stand out, sell, add value, and service new and existing customers has become MORE valuable...who would have predicted that? Thanks Al!
