If your contact is busy when you call, ask if you can call back. Get a specific time and day to do this, and add the call to your to-do list for that day. Be sure to call back at the specified time, the employer may give you an interview just because you didn't push when they were busy and called back at the appointed time. Ask to Call Back From Time to Time Ask if they would mind if you keep in touch. Maybe they will hear of an opening or have some other information for you.
Many people get their best leads from someone they have checked back with several times.
It is important to follow up with each person you contact. This can make a big difference in their remembering and helping you in the future. It is just good manners to send a thank-you note to someone who helped you. People will also be more likely to help you in the future if you let them know that you appreciate their help. Send your thank-you note right after the phone call so you don't forget .
