UCSD MSBA 面经整理 [2020.05.08]

[日期:2020-08-20] 来源:ChaseDream论坛 作者:云雀落樱 [字体: ]

谁能想到 UCSD 如今还在发 offer 呢?

Timeline:

  • 11 月下旬交齐材料(赶的是 12.01 R1 的 ddl)
  • 02.15 做完 kira
  • 5 月收到录取……(3 月到 4 月期间发了若干类似 love letter 的东西,都被打太极已不痛不痒的方式回复了,真的已经绝望)

谁能想到? lz 其实已经做好去大森林的准备了,但是森林一直没有给应对疫情的举措,超级害怕一直网课,所以如今 SD 捞了我不如就从了他……真香。

不敢说我的面经是全站最全的,但一定是为数不多带答案的,造福后人。 当时被估计题弄的脑壳痛,最后面试的时候遇到的是估计“大海中有多少条鱼”,用抽样估计的思路去回答的,这一套路也可以用来估计“树林中有多少只猴子” “草原上有多少匹马” 笑死 对这个项目感兴趣的小可爱看这里,搬运了一下资料:

Writing

  1. 项目经历 It’s important to be able to describe complex ideas in simple terms. Think about a complex problem you worked on recently. Please write an email describing this problem to an acquaintance who doesn’t have a technical or quantitative background. Be sure to describe the original issue and goal, your approach, the tools used, the solution and/or outcome, and what you learned.
    Dear XXX
    It is my pleasure to describe this problem which occurred yesterday and its solutions to you.
    In this case, I was required to analyze reasons for severe sales decline of Mini channel in west China based on the sales data so as to assist the fund allocation strategy. I extracted data of Mizone beverage from database and accessed it through pivot tables in Tableau. By disassembling the sub-channels, I found it was the clients who originally belonged to Mini in 2018 but converted to CVS in 2019 that resulted in shrink of Mini channel. Therefore, it was still necessary to invest money on mini channel rather than give it up. This precious case allows me to see through surface of data and get essence of business, during which I had a deeper understanding of the combination of data and business.
  2. 学校的 faculty 会时常与学生讨论分享一些学生所关心的问题,写封邮件给一位 professor,约他一起讨论问题。
    Rady 的学生都要跟老师多 make connections.请写一封邮件给你一个 professor,请求见一面讨论一个 course related problem. Dear Professor XX
    I am Sunny in your class this semester. I met some trouble when doing the project based on the data you provided. I have tried all kinds of methods but still failed to draw the correct graph on the dashboard. I feel really disappointed and eager to your help.
    I would like to know whether we could have a discussion recently so that you could give me some useful suggestions about my problem? Please let me know if you are available this week!
    Best wishes
    Sunny
  3. Rady School 的一位 alumni 很愿意用开咖啡茶话会的方式跟学生探讨将来找工作的事,并为在校生提供工作机会等等。请你写一封邮件,跟这位 alumni 约一次 after lunch coffee meeting 大致是这个意思。
    Dear friend,
    How is it going? I’m Sunny, who is going to join in MSBA program in Rady business school this autumn. Hearing that you are willing to share valuable information about job searching, I am eager to have a discussion with you! According to the information on homepage, this program is career-oriented and lasts for only 12 months, so it seems to be quite demanding for international students to find an ideal job with hardcore knowledge and limited time. Therefore, I do hope to make early preparations for internship or full-time positions such as job opportunities and career path for Business Analytics students. I know you are really warm-hearted and may have an enlightening view about the problems bothering me, so I sincerely hope to invite you to in the café next to your office this weekend. Please let me know if you are available!
    Best wishes
    XXX
  4. 假设你是 rady 的一名校友,写信给一个 Admission Committee 推荐你的一个同事或朋友。The decision to join the Rady MFin program is one that will forever become a part of your identity as a future alumnus of the School. Our graduates are great recruiters because they have been through the MFin program and know what it takes to be successful. Imagine that you are a Rady alumnus, and write an email to the Admissions team recommending a colleague or friend to the MFin program.
    Dear officer in admission committee,
    How is it going? This is Sunny, the graduate from Rady business school three years ago. Thanks to this program, which provided me with the best platform to strengthen my professional competence and rich alumni resources, I finally realized my long-cherished career goal as a business analyst. Today, I sincerely recommend an applicant who matches well with the student profile of MSBA program.
    I met her in the company where I work in and she is the intern in our team. Overall, she is highly intelligent and has good analytic skills. She is proficient in applying SQL to acquiring and processing data in complex business scenarios. Furthermore, she is a well-disciplined, industrious girl with a pleasant personality. She goes well beyond the requirements in the quantity and quality of our projects, showing great perseverance and initiative. If her performance in my team is a good indication of how she would perform as a graduate student, she would be an extremely positive to MSBA program!
    Please do not hesitate to contact me for further information. I do hope this program could scale new heights and admit more excellent students! Best wishes,
    XXX
  5. Rady 会邀请很多 speaker 来演讲,会有很多 student 和 alumni 来听,请写邮件邀请一位你在 speaking event 里面遇到的人(应该是指学生和校友,到时候再仔细看看吧)参加社交活动。
    Dear XXX
    Warm greetings from Sunny! How is it going recently? It’s my pleasure to meet you in the speaking event last weekend and I was impressed by your humorous words. I heard that a social club activity is going to be held this weekend in the lion building, which aims at promoting communication among students in business school. I consider it to be a great chance to make new friends and know more alumni who are willing to share career opportunities with us. Do you want to go with me together?
    Please let me know if you have time!
    Sincerely,
    XXX
