向您请教：申请工签时，填写《Employment Supplementary Form》时遇到的问题:

manchuguan

老板已在trademe上登广告，并已对应聘者逐一面试。最后选中了我。

请问：老板如何证明他确实面试了这些人呢？如果单是把广告页面打印出来，
           也只能证明他打了广告，并不能证明他面试了这些人呀？

谢谢

表格上原文：
C2 Have you used other advertising media such as national newspapers, internet etc?
     Yes. You need to attach dated copies of the advertising. You also need to attach evidence of the outcome of your advertising.
