secondly , my personality has been changed a lot during my college life. when i was a senior high student all i had to do is study but since i came to tongji university i joined many communities like the english corner, the climbing club, the drama club. my life became very interesting and since these communities are organized by students , we communicated a lot and had fun together , besides i learned how to communicate an cooperate with others. this helps me in my study. when i do team work with my fellow students , i know how to do to be in a team.

[外贸跟单英语面试自我介绍

评委老师好：

我是来自山西临汾的考生。我的名字是“栋梁之材”颠倒过来的梁栋，普通的名字中包含了父母对我的深深期望。父母对我的教育始终坚持一个原则：给予充足的空间发展自己，正是在这样一个自由、放松的家庭氛围中造就了一个活泼、开朗、充满朝气的我。在生活中，我是一个大大咧咧女孩，甚至有些粗心大意，经常惹出一些笑话让周围的人哭笑不得。接触编导这个专业后，让我对生活中普遍存在的电视、电影有了新的认识，一部作品从开始准备到最后呈献给观众，有太多幕后人员的付出与心血。他们那种甘居幕后的精神深深影响了我，因此我怀揣梦想选择在这条道路上勇往直前。正如那句话：既然选择了远方，便只顾风雨兼程。谢谢老师。

大家下午好 !

我是来自上海交通大学市场营销专业的xxx。我喜欢读书看报，因为它能丰富我的知识;我喜欢跑步，因为它可以磨砺我的意志，我到底是个什么样的人呢?我是一个活泼开朗、热情、执着、有坚强意志的人。既然今天竞聘的是营销经理一职，我想谈谈自己对营销的理解。营销不等同于推销，但推销是营销的重要组成部分。要想做好营销工作，首先就要做好自我推销。让一个陌生人信任自己是有一定难度的，但只有客户相信可以，才会相信自己的产品，才能更好的将产品推入市场。我想"做人，做事，做生意"大概就是这个意思吧!

我觉得作为一名营销经理，除了应该具备一定的营销知识外，还应具有良好的沟通、协调能力，能够吃苦耐劳，具有良好的团队合作精神，讲究职业道德。身为班长的我，在三年的时间里，组织了班级各种各样的活动。通过组织这些活动，提高了自己的组织协调能力，加强了团队合作意识。同时也让我充分认识到，个人的能力毕竟很有限，只有通过团队合作，集思广益，取长补短，才能更好的完成工作。如果这次我有幸竞聘上营销经理，我想打造一个平台，让自己的同事在一种轻松却不失严谨的氛围中工作，大家相互合作，具有良好的团队精神。

同时我认为，营销也是一种服务。既然是一种服务，就应该做到让大家满意，用热情和真心去做。激情，工作中不可或缺的要素，是推动我们在工作中不断创新，全身心投入工作的动力。激情加上挑战自我的意识，我相信我能胜任这份工作。

"诚信是我们合作的基础，双赢是我们共同的目标!"我愿与xx文化一起发展，一起创造辉煌的历史。

我是&&，是&&学校&&专业的毕业生，我学习的是自动化专业，我自己本身对这个专业很喜欢，在大学期间，我学好了专业知识，能力得到了提升。

机遇偏爱有准备的头脑。不断挑战、不断完善是支持我在大学四年中进取的不竭动力。母校踏实严谨的学风使我树立了勤奋刻苦、敏捷思辨、努力求知的学习态度，扎实的专业知识和熟练的计算机技能相结合的知识结构，是我的一大优势。在专业基础学习中，我学习了电子电路设计软件，单片机,plc可编程控制器等，善长于电子电路的开发与设计及单片机的应用。我深知，作为一名电类学生，掌握计算机应用的必要性，先后学习了多种计算机编程语言c、汇编语言等，能熟练掌握与应用office、windows xp，顺利的通过计算机等级考试，取得了良好的成绩。

“一万年太久，只争朝夕”。时间不等人，不超越时间的人将被历史淘汰。拿破仑说过：“不想当元帅的士兵不是好士兵”。我要说“不想干出一番事业的职员也不是好职员”，我要与风赛跑，我相信实力与魅力征服一切，但我更希望能在最年轻、最有能力、最有挑战意识的时间里培养、体现自我价值，成长为能吃苦，能战斗的英才。因为年轻，所以我要有干劲和信心;因为年轻，我也有缺点和不足。但我愿在新的环境中与其他同事共同学习、共同进步、共同创造企业财富。

思考、创新、追求、给予，是我不变的人生信条。我希望自己能在以后的日子里，能够做得更好。

翁去八百载，醉乡犹在; 山行六七里，亭影不孤。我来自风景秀丽的XXX的一所省重点XXXX学校，我叫。

我出生在一个xx家庭，从小受到良好的文化熏陶，善解人意。十八岁的我自信、洒脱，有着良好的交际能力。也有着打篮球，爬山、跑步等业余爱好。我喜欢听抒情音乐，背抒情诗，看小说，英语、聊天、哼歌。老师都说我是个永不疲倦的乐天派。

从小的我就渴望翱翔蓝天，能够为世界各地的朋友做好热情周到的服务是我的荣幸。我知道作为一名空中乘务员，不仅要有服务他人的满腔热忱，还要有隐忍、宽容、海纳百川的胸襟。这是关系国家形象的光荣而又神圣的事业，我会关心别人的感受，学会沟通，学会微笑，学会享受飞翔带给自己和他人的快乐。

也许，我还稚嫩，离那个梦想还缺少很多条件，但是我会努力，去学习更多的东西来充实自己，也渴望从评委老师这里得到一次让梦想飞翔的机会。我相信，当梦想被赐予一双翅膀，飞翔再也不是一种渴望。我知道我的梦想就在那片更高的天空，我要用纯真的心灵去感化着每一位一闪而过的旅客。谢谢!

[面试中的英语自我介绍

评委老师们：大家好!

翁去八百载，醉乡犹在; 山行六七里，亭影不孤。我来自风景秀丽的琅琊山脚下滁州市的一所省重点中学，我叫xxx.

我出生在一个xx家庭，从小受到良好的文化熏陶，善解人意。十八岁的我自信、洒脱，有着良好的交际能力。也有着打篮球，爬山、跑步等业余爱好。我喜欢听抒情音乐，背抒情诗，看小说，英语、聊天、哼歌。老师都说我是个永不疲倦的乐天派。

从小的我就渴望翱翔蓝天，能够为世界各地的朋友做好热情周到的服务是我的荣幸。我知道作为一名空中乘务员，不仅要有服务他人的满腔热忱，还要有隐忍、宽容、海纳百川的胸襟。这是关系国家形象的光荣而又神圣的事业，我会关心别人的感受，学会沟通，学会微笑，学会享受飞翔带给自己和他人的快乐。

也许，我还稚嫩，离那个梦想还缺少很多条件，但是我会努力，去学习更多的东西来充实自己，也渴望从评委老师这里得到一次让梦想飞翔的机会。我相信，当梦想被赐予一双翅膀，飞翔再也不是一种渴望。我知道我的梦想就在那片更高的天空，我要用纯真的心灵去感化着每一位一闪而过的旅客。谢谢!

尊敬的各位考官、各位评委老师：能参加今天的面试，并向各位考官和评委老师学习，我很高兴。同时通过这次面试也可以把我自己展现给大家，希望你们能记住我，下面我简单介绍我的基本情况。

我叫，今年岁。毕业于。我性格活泼开朗，大方热情，乐于助人，平时喜欢阅读、看书和上网流览信息。我曾经在学校参加过教学实习，在实习期间我严格按照正式老师的标准来要求自己，进行语文教学和班级管理。我深入学生，和他们相处融洽，和他们一起布置文明教室，开主题班会，组织大家开展篮球赛，参与诗歌朗诵比赛等，学习了语文教学的各种知识，掌握了一定的中学语文教学技巧，也对班主任工作和学生工作有了一定的认识，找到了自己的管理班级的一套方法。同时，在实习当中，身边教师无私奉献的精神和天真、求知若渴的学生们勤奋的学习态度深深地感染了我。我也深深体会到了作为一名“人类灵魂的工程师”的乐趣和重要意义，更加坚定了自己做一名教师的决心，成为一名教师也成了我的愿望。教师这个职业是神圣而伟大的，他要求教师不仅要有丰富的知识，还要有高尚的情操。为了成为一名教师，我在自己掌握了专业知识的基础上，不断拓展自己的各种能力，培养自己的爱心、责任心和耐心，创新能力、竞争能力和分析、处理问题的能力，并参与各种活动，广泛培养自己的兴趣爱好，并学有专长，做到除擅长写作和气排球外，还能会唱、会说、会讲。“学高仅能为师，身正方能为范”，在注重知识学习的同时我还注意培养自身的道德情操，自觉遵纪守法，遵守社会公德。使自己具有一名教育工作者应该具备的最起码的素养。如果，我通过了面试，成为该校教师队伍中的成员，我将继续虚心学习，努力工作，发挥自身所长，为教育事业贡献自己的一份力量，决不辜负“人类灵魂的工程师”这个光荣的称号。

比起我的竞争对手在年龄上我已不再有优势，但是我比他们更多了一份对孩子的爱心、耐心和责任心，更多了一份成熟和自信。教师这个职业是神圣而伟大的，他要求教师不仅要有丰富的知识，还要有高尚的.情操。因此，在读师范时，我就十分注重自身的全面发展，广泛地培养自己的兴趣爱好，并学有专长，做到除擅长绘画和书法外，还能会唱、会说、会讲。“学高仅能为师，身正方能为范”，在注重知识学习的同时我还注意培养自己高尚的道德情操，自觉遵纪守法，遵守社会公德，没有不良嗜好和行为。我想这些都是一名教育工作者应该具备的最起码的素养。

各位考官好，今天能够站在这里参加面试，有机会向各位考官请教和学习，我感到非常的高兴。希望通过这次面试能够把自己展示给大家。今年…岁。汉族，法学本科。

我平时喜欢看书和上网浏览信息。我的性格比较开朗，随和。能关系周围的任何事，和亲人朋友能够和睦相处，并且对生活充满了信心。我以前在检察院实习过，所以有一定的实践经验。

在外地求学的四年中，我养成了坚强的性格，这种性格使我克服了学习和生活中的一些困难，积极进去。成为一名法律工作者是我多年以来的强烈愿望。如果我有机会被录用的话，我想，我一定能够在工作中得到锻炼并实现自身的价值。

同时，我也认识到，人和工作的关系是建立在自我认知的基础上的，我认为我有能力也有信心做好这份工作。公务员是一个神圣而高尚的职业，它追求的是公共利益的最大化，它存在的根本目的是为人民服务，为国家服务。

雷锋说过:人的生命是有限的，而为人民服务是无限的，我要把有限的生命投入到无限的为人民服务当中去。这也是我对公务员认知的最好诠释。所以，这份工作能够实现我的社会理想和人生价值，希望大家能够认可我，给我这个机会!

我叫xx， 您可能会联想起琼瑶小说， 字的确就是那两个字， 差别就是人没有那么漂亮， 呵呵。其实， 我的同学更都喜欢称呼我的英文名字， 叫June， 六月的意思， 是君的谐音。

我来自广东的恩平市， 可能您没有去过， 是一个很小的县级市， 这几年刚刚开发了温泉业， 我想将来会有更多的人了解这个小城市。

在20xx年我以恩平市全市第一名的成绩考上了中山大学， 学的是计算机科学专业。 不过， 在中大， 我没法再像高中一样总是名列前茅了， 到目前为止， 我的综合学分排名是40%左右。在专业课程方面， 我C++的编程能力比较强， 一年以前就开始自学java， 在班级里是最早开始学Java的。

我参与过我们老师领导的一个项目， 叫做LAN聊天室， 我负责开发了其中的及时通信系统的编写。在我们班， 老师只挑选了我一个女生参与这个项目， 主要是我写程序的效率比较高， 态度也非常认真。

除了学习和项目实习以外， 我在学生会工作了两年， 第一年做干事， 第二年被提升为秘书长。大家对我的评价是考虑问题很周全， 令人放心。

在我的求职清单上， IBM是我的首选单位， 原因和您面试过的很多同学都一样， 出于对大品牌的信赖。毕竟， 大品牌公司意味着很多我们需要的东西， 比如培训和薪资， 能和优秀的高素质的人在一起工作等等。

技术支持工程师也刚好是我的首选职位， 因为我有技术背景， 也有作为女性和和客户沟通的天然优势。还有， 我不担心频繁出差， 因为我身体素质很好， 我已经坚持晨跑两年多了。在IBM专业技术方面， 我信赖公司的培训体系和我自己的快速学习能力!希望能有机会加入IBM团队!
