4、ymotherisaworker会计学面试时需要做自我介绍,这个时候不要细致地谈自己的生活情况或者工作经验,而是要想方设法地让面试官对你有所了解,告诉他些事情,这些事情应该使你在招聘过程中具有优势。或许你想选取些有人情味的故事讲给他听,但这么做,你要有把握与面试官的想法吻合。或者可以概述下最近你干的工作和你正在申请的工作有什么联系,有怎样的帮助,以及你为什么要到这家公司工作等等。特别值得提的是,要举例子,这样你的回答才更具真实性,更容易被接受,才能给对方留下深刻的印象。或者当面试官让你做自我介绍的时候,你可以主动问下对方想知道自己哪方面的情况,这样也便于你的回答更加有针对性。但是这种做法的前提是你对面前的这个面试官有定的把握,确信这样追问不会引起对方的反感才行。面试小常识LessonReviewIseeMrJohnWatt,thepersonnelmanager?haveeatyourinvitationforaninterviewisagreatpleasureformetohavethisopportunityforinterviewIhaveyourname?wereyouborn?isyourage?isyourhometown?isyournative/permanentplace?longhaveyoubeenmarried?IhavebeenmarriedfortwoyearsYourTopicGoesHereEducationBackground教育背景篇每个企业和单位都比较看中应聘者的学历,高学历在定程度上也代表着高能力和高素质。即使你的学历很高,在表达上也应该注意些技巧,那么学历不是很高的求职者就更要注意如何介绍自己的教育背景了。面试小常识YesIwasawardedascholarshipfromtheuniversityeveryyearWhichuniversitydidyougraduatefrom?Whatdegreewillyoureceive?IgraduatedfromHebeiUniversityImajoredinEconomicsHowaboutyouracademicrecordsatcollege?Didyougetanyhonorsandawardsatcollege?IwillreceiveaBachelor’sdegreeInfact。
