highlight your strength, prepare succinct answer to each question, usually 2-3 sentences. You should practice until you feel confident about the common questions. A mock interview with your hubby might be helpful.

Besides, don't talk to much. The more you talk, the higher the chance that you will disclose your weakness. You should not exceed 40 percent of the content of phone conversation. Otherwise, it is not wise.

Another suggestion: go to bookstore, you can educate yourself by reading tons of books such as interview skills including phone and onsite.

Good Luck! Be confident!
