I've been helping my aunt get her house ready for sale, and it's given me some insight into the resume writing process, believe it or not. Like their homes, people have an emotional attachment to their work history. That's usually the case with a PITA (Pain-in-the-you-know-what) clients. They could be insecure about some aspect of their work history, defensive about their age, reluctant to speak too highly about their former contributions so their next employer won't "expect too much." Or, they might just be nervous about the job search process, and any excuse to postpone finalizing their resume (even if they initiated contact in the first place) means they actually have to confronth fs and start looking.
I was originally going to write in this blog post about why first impressions on the resume are so important -- but I almost think it's more important for you to pay attention to first impressions with your clients.
Is it a wife calling for a husband? Does the person mention feeling unsure about their prospects for work after being employed with the same company for a number of years? Do they seem unfocused, or unsure of their job target? All of these are first impressions -- and how you handle them will be critical to your success with the client.
