2025/3/18 中午的Mini case, 遇到地上面有人分享的Energy One的題目:. Χ\n\n面試官先稍微自我介紹, 然後問我的背景, 這邊記得還是得稍微準備一下, 我太專注在mini case準備所以講得比較粗略\n再來開始進入主題, 有一家能源公司叫Energy One, 最近想從Fossil fuels transition to renewable power\nQ1: What factors do you consider for this transition?\n基本公式回答: 1. Market trend 2. Financial feasibility 3. Competitors 4. Brand awareness 自行添加細項\nQ2: 計算題, Power Plant Capacity 8.8m MW/H a year, lease cost $5m/month, FC $25m/year, VC $20 per MW/H, Sales price: $40 per MW/H, Initial investment $400m, how many MW/H produce of return can cover 10% of initial investment?\nset we can cover 10% back with X MW/H produce\nR - lease cost - FC - VC = 40m\n40X - (512) - 25m - 20X = 40m\n\nX = 6.25m\nQ2延伸: 這邊面試官問我6.25m make sense嗎? 我一開始沒聽懂, 他才說因為maximum capacity 8.8m MW/H, 所以6.25m make sense\nQ3: 呈上題, 如果今天Government限制一家公司只能生產5m capacity from fossil fuels, what other sources we can tap into?. ----\n這邊因為已經準備過所以回答得很輕鬆, 不過如果是第一次回答可能會回答不上來\n我回答: Anything that can keep the stable profitability, like Solar, Wind, and Hydro, 然後稍微說了一下each pros and cons 等等\nQ3延伸 (這題應該是考官自己加的, 練習時沒看到): 如果決定不tap into new power, 有什麼方法可以keep the profitability?\n答: 根據R & C 和 Supply & Demand 來回答, 1. Set a higher price 2. Lower cost 然後稍微提到可能有那些能變動\nQ4: 呈Q3, 公司決定Build 2 mini test plants, one is Solar, one is Ethanol to produce additional power,\nSolar: Initial investment: $12.5m, in a year, 75% of time is sunny days produce 150k MW/H, 25% of time is cloudy days produce 50k MW/H, VC = 0, still sell $40 per MW/H, How many years needed to cover initial investment?\nset X years needed to cover initial investment,\n(150k75% + 50k25%)40X = 12.5m\nX = 2.5\nEthanol: Initial investment: $2.5m, in a year, produce 100k MW/H a year, VC = $30 per MW/H, sell $40 per MW/H, How many years needed to cover initial investment?\nSet y years needed to cover the initial investment\n100k(40-30)y = 2.5m\ny = 2.5\nQ5: 呈上題, Which test plant do you recommend?\n答: 這邊我問了有沒有任何的Budget limit, 面試官說沒有, 所以我說Solar 因為 VC = 0 但 75% sunny 25% cloudy 比例可能不穩定, Ethanol 因為VC不固定加上很多原物料從外國進口, 之後的profit很難說, 所以long term來說肯定是Solar\n後面就是一些閒聊, 問面試官問題\n. Waral dи,\n\n這題其實已經練過了, 我還寫了幾張筆記在旁邊, 結果真的就考到了, 其實全程我都已經有答案了但還是要裝一下問一些clariy questions 哈哈, 這題要注意數字都很大, milloin跟k放在一起很容易緊張就算錯, 要細心一些\n大概過一個小時HR就打來說面試通過了要安排3月底或4月初的 Power Day, 這邊也想問有沒有也要準備Power Day的夥伴可以一起討論! 也順便找人Mock Interview, 有償! 可再討論!\n感謝各位, 希望大家面試順利, 順便幫之後的Power Day集氣!
