面試必知:Brainteaser答題技巧



「How many traffic lights in Hong Kong?」
「What seven-letter word has hundreds of letters in it? 」

好多時候係大公司Intern或者Grad Job面試都會遇到以上BrainTeaser問題,有小小似IQ題,答案較無凌兩可。好多同學仔覺得呢類問題好考急材,好難Prep同好易GG,但其實都唔係完全冇得準備,今次係呢篇Brainteaser大全入面我地會同大家分析Brainteaser 種類及答題方法。
如果你地黎緊有面試或者黎緊會報Intern/Grad Job(特別係Consulting同Tech Firms),呢個Article會非常有用。

❗️首先,同學仔要理解Brainteaser背後想評核既各種技能:
解決問題能力。Brainteaser問題種類層出不窮,而當中會牽涉好多大大小小問題,面試官會希望係答案入面睇到Candidate解決問題能力。
批判思考能力。因為問題好多時候冇絕對答案,好多時候面試官係想知道Candidate既思考模同埋邏輯。
創意。Brainteaser係冇一套絕對答題技考,所以Candidate要突破自己思考既框框去諗Solution。
抗壓能力。當Candidate得10到20秒時間要去接觸從未準備過既問題,難免會緊張,所以都能夠考驗抗壓能力。面試同時亦可模擬日後Candidate需要短時間內作决定既能力。

❗️其次,我地都會羅列四種主要既Brainteaser問題種類,等同學仔可以準備同埋嘗試思考答題模式。

食字:
- What two words, when combined, hold the most letters? - Post Office
- I always drive my customer away. Who am I? – Taxi Driver
-What seven-letter word has hundreds of letters in it? – Mailbox
計數
- How can the numbers 6, 1, 7 and 9 be arranged to make 24? - (9 – 6) × (1 + 7) = 3 × 8 = 24
-Perform this calculation in your head, mentally adding the numbers as quickly as you can. Start with 1000 and add 40. Now add 1000. Add 30 to that, then add another 1000. Now add 20 to that result. Add another 1000 and finally, add 10 to that. What is the total? - 4,100. If you got 5,000 you‘re not alone. 96% of test subjects get the wrong answer.
圖畫
Brainteasers都會出現類似Aptitude Test Logic問題,經係果啲圓形、三角形、方形排列,某個位會出現咩圖案等得。
邏輯
-How many traffic lights in Hong Kong.
-How to measure the weight of an elephant without a scale

❗️❣️最後亦都係最重要,究竟有咩答Brainteaser題目既技巧:
多角度思考/作出Assumption
好多Candidate聽完問題之後就立即Gut Feeling沖口而出,但係好多時候題目好短,其實講出絕對答案之前,可以講多啲你會作出既Assumption同埋盡量多角度思考。
重點:思考模式
因為Brainteaser 冇絕對既答案,所以好多時候點樣去闡釋個答案遠比個答案本身重要。
多啲練習令自己有答題感覺
最後,雖然你冇辦法預先知道面試題目,但Brainteaser 既出法不外乎食字、計數、圖畫、邏輯,上網睇多啲會幫助到你有答題既感覺。
