The best way to go about this is to have a "selling proposition."
Start by identifying the needs and opportunities faced by employers most likely to hire you. Then think about how you’ve met similar challenges in the past and received good results. Next, craft a brief statement that gets right to the point.
Your next step is a communication strategy. Do you have any liabilities? A good communication strategy will first get across how you’ll contribute. But, Gerberg stressed it also needs to neutralize or even turn to an advantage any liabilities.
Any experience you have in a related field to your own, expand so you can be more marketable and be able to do more for a future employer.
