為您的職業奮鬥的各位好！我們是 ProgramHelp 團隊。我們擁有豐富的學生指導經驗，並從「1Point3Acres」等平台汲取心得，因此我們了解找到科技工作所面臨的挑戰，尤其是在以下領域 DoorDash.我們將提供深入的分析 DoorDash interview process and key focus areas to help you succeed.
DoorDash 面試流程概述： 知己知彼，百戰百勝
履歷篩選
這是第一道關卡。一份能突顯您的優勢，並與工作要求高度一致的履歷表非常重要。確保清楚呈現您的專案經驗與技術堆疊。
線上評估 (OA)
有些職位可能會有一輪 OA 測試，通常是測試演算法和邏輯推理問題。此階段評估應徵者的基本技能。
Phone Screen
通常由一或兩位面試官進行，時間約為 45 分鐘至一小時。此輪面試主要著重於
- Self-Introduction & Behavioral Questions:自我介紹 & 行為問題： 清楚說明您過去的經驗，展現您的溝通、團隊合作及解決問題的技巧。準備好使用 STAR 方法回答「說一說......」的問題。
- 技術問題 & 編碼： May involve fundamental data structures, algorithm knowledge, and require completing 1–2 coding problems online. The difficulty istypically LeetCode easy to medium.
虛擬現場訪談
如果您通過電話篩選，下一步就是幾輪更深入的虛擬現場面試。這通常是重頭戲，包括多個階段：
DoorDash interviews typically cover:
- Coding Interviews (2–3 rounds, 45–60 mins): Solve 1–2 algorithmic problems. Assesses problem-solving approach, code quality, edge cases, and communication. Common topics includegeographic calculations, pathfinding, and data processing/filtering.
- System Design Interview: 主要針對有經驗的角色 (其他人應有基本的瞭解)。專注於設計開放式系統 (例如：訂單派遣、審查)。評估需求分析、設計選擇、可擴充性、可靠性及權衡。
- Behavioral Interview / Hiring Manager Chat: 可以是專門的一輪，也可以混在其中。專注於團隊契合度與職涯目標 (尤其是招聘經理)。
DoorDash Interview High-Frequency Real Questions
1: Coding Challenge
Question: Design a function findNearbyRestaurants that accepts four parameters:
userLocation: A tuple or object representing the user’s current location, e.g.,(latitude, longitude).allRestaurants: A list of restaurant objects, where each object containsname(string),location(tuple or object), andrating(float).maxDistance: A float representing the maximum search distance the user is willing to accept.minRating: A float representing the minimum restaurant rating the user requires.
The function should return a list of restaurant names that meet the following criteria:
- Their distance from the user is within
maxDistance. - Their rating is not less than
minRating. - The returned list should be sorted by distance from nearest to farthest; if distances are the same, then sort by rating from highest to lowest.
You need to:
- Describe how you would calculate the distance between two geographical coordinates.
- Implement this function in your preferred programming language.
- Discuss the time and space complexity of your solution.
- (Follow-up) If the number of restaurants is very large, how would you optimize this search process?
Focus Areas: Data structures, sorting algorithms, geographical distance calculation logic, complexity analysis, large-scale data processing strategies.
2: System Design
Question: Please design DoorDash’s Estimated Time of Arrival (ETA) system.
You need to consider:
- Core Functionality:
- Provide users with an initial ETA when browsing restaurants and placing an order.
- After order confirmation, provide a dynamically updated ETA.
- Display ETA to customers, restaurants, and Dashers.
- Key Factors: List factors like restaurant preparation time, Dasher assignment time, travel distance, traffic conditions, weather, etc.
- System Architecture:
- Main components (e.g., ETA calculation service, data collection service).
- Data flow and storage choices.
- ETA Update Mechanism: How to adjust ETA and notify parties when conditions change.
- Challenges & Trade-offs: Accuracy vs. performance, handling uncertainty, scalability.
Focus Areas: Business requirements, component design, real-time processing, scalability, reliability.
3: Behavioral Question
Question: “Tell me about the most complex technical challenge you faced on a project. How did you analyze and solve it? What did you learn? If you could doit over, what might you do differently?”
Focus Areas:
- Problem-solving methodology.
- Technical depth.
- Handling pressure and uncertainty.
- Teamwork and communication.
- Learning and self-reflection.
- Decision-making and accountability.
Tip: Use the STAR method (Situation, Task, Action, Result) to structure your answer.
