Deloitte S&O上岸复盘：Profitability & Market Entry Case实战详解

刚拿到Deloitte Strategy & Operations (S&O) 的Offer。回顾整个面试流程，S&O的风格介于MBB的Pure Strategy和Big 4的Implementation之间。他们既看重战略逻辑，又极度关注落地可行性 (Feasibility)。

以下是两轮面试中印象最深的实战Case复盘。

Round 1: Market Sizing (The Logic Check)

Topic: "Estimate the total volume of coffee beans consumed in NYC annually."

考点: 逻辑拆解的颗粒度 + 常识 (Common Sense)。 我的解法 (Supply + Demand Mix): 将消耗分流为两端：

Home Consumption (家庭端):
- NYC Population -> Coffee Drinkers % -> Cups/Day -> Grams/Cup.
- Key Assumption: 假设每个Shot用18g粉。
Commercial Consumption (咖啡店端):
- Types of Shops (Chains vs Independent) -> # of Shops -> Avg Traffic -> Cups/Day.
- Sanity Check: 交叉验证。比如算出一家店每天卖500杯，问自己这在NYC是否合理？

Feedback: 面试官表扬了我对“浪费率 (Wastage)”的考虑（咖啡店每天倒掉的陈豆），体现了Business Sense。

Topic: "A CPG client's profits are declining. Find the root cause and fix it."

分析路径:

Profit Tree Breakdown:
- Revenue (Flat) vs Cost (Rising).
- Cost -> Fixed vs Variable.
- Root Cause Found: Raw Material Cost increased by 30%.
Strategic Solution (The Deloitte Way):
- 单纯说 "Raise Price" 是不够的。
- Short-term: Hedging strategy for commodities (对冲原材料波动).
- Mid-term: Reformulate product (减少昂贵原料占比而不影响口感).
- Long-term: Vertical integration (收购上游供应商).

Why I Passed: 面试官不仅要“分析问题”，更想要“解决方案”。特别是当我提到 Hedging 和 Formula Reformulation 这种operational level的建议时，面试官眼睛亮了。这非常符合S&O "Strategy that works" 的定位。

Be Practical: 不要只给天马行空的战略。Deloitte的客户需要明天就能落地的方案。
Interaction: 把面试官当成Client。在Round 2中，我不断通过 "Do we have data on X?" 来引导面试官给出Clue，而不是自己瞎猜。
Show Enthusiasm: 展示你对Ops, Supply Chain或Digital Transformation的真实兴趣。
