Nuestro proceso de contratación

  • You’ll kick things off by meeting with a member of the Talent Acquisition team to talk about the role and your experience. This is a strategic conversation about how your background and technical skillset align with the position.

    How to prepare:

    • Craft your elevator pitch: Be ready to answer the classic "Tell me about yourself" question. Provide a clear, concise overview of your career, key technical projects, and top accomplishments.
    • Know why Uber: Be prepared to explain why you’re excited about this role at Uber and how it aligns with your goals and values.
    • Understand the role and context: Research the role you’re applying for, the market it supports, and the specific Uber business line. Understand how your skills align with the team’s needs.
    • Know the technical stuff: Get ready to tackle technical questions on Big-O notation, CS fundamentals, and domain-specific topics.
    • Prepare thoughtful questions: Have insightful questions ready to ask at the end of the interview, showing your genuine interest in the role and the company.

    During your interview:

    • Highlight key technical projects: Share examples of impactful projects you’ve worked on, focusing on technical challenges, your approach, and measurable outcomes.
    • Demonstrate your understanding of core concepts: Be ready to talk about key engineering topics like scalability, clean architecture, or dependency injection, depending on the role’s focus.
    • Ask clarifying questions: If you’re unsure about a question or expectation, don’t hesitate to ask. We appreciate candidates who seek clarity.
  • This pair programming interview focuses on problem-solving using HackerRank, covering both Coding and Design & Architecture (D&A). Our goal is to evaluate your coding ability and better understand the complexity and scope of your prior projects using a D&A lens—not to conduct an exhaustive review of your technical depth or design expertise. This serves as an initial evaluation to determine if you qualify for the business interview rounds at the appropriate level.

    Interview Structure:

    • ~45 minutes: Coding
    • ~15 minutes: Design & Architecture
    Coding language to prepare:

    • Your choice. Choose your language wisely and ensure you're highly proficient in it.
    How to prepare:
    • Practice coding: Refresh your coding skills, especially if you’re rusty or unfamiliar with paired coding. Solve a few problems with varying difficulty using platforms like LeetCode. Continuously test your code. Focus on:
      • Common data structures and algorithms (e.g., hash tables, trees, stacks).
      • Data structures, particularly the ones used most often (e.g., arrays, stacks (or queues), hash tables, trees, graphs, and heaps).
      • Runtime analysis (Big-O notation) and optimization techniques.
      • Problem-solving approaches: Practice solving scenarios common in large-scale tech companies.
    • Refresh yourself on Design & Architecture: Be prepared to discuss a project that highlights the complexity and scope of your role, including architectural components and design decision-making. Be ready to discuss trade-offs: Why was one technology chosen over another? What was the reasoning behind key decisions?
    During your interview:
    • Provide a solution on HackerRank: Be ready to write and explain your solution in a live coding environment.
    • Ask clarifying questions: Analyze the problem and make sure that you fully understand it before jumping in. It’s OK to ask clarifying questions during the interview to make sure you understand the exact problem you are trying to solve. Also, breaking down the problem into smaller pieces can be helpful.
    • Account for edge cases: Think through and address edge cases to show thorough problem analysis. One technique to write a better solution is to consider what you would catch if you were code reviewing your code.
    • Communicate your thought process: Walk the interviewer through your reasoning as you solve the problem. Before implementing, discuss your proposed solution to ensure alignment.
    • Keep things simple: If you find the solution getting excessively complex, step back and ask if there’s a simpler way to solve it. It may also be helpful to write everything out so you can see insights and bugs faster and make fewer mistakes.
    • Test and debug: Continuously test your code and handle exceptions to confirm your solution works.
    • Write clear, readable code: Use meaningful variable names and keep formatting consistent for easy understanding.
    • Engage with follow-up questions: Be prepared to dive deeper into your solution and discuss alternative approaches or improvements.
    Other:
    • Reflect on impact: Think about the scope and results of your past roles and how they relate to solving problems at Uber.
    • Review the job description: Identify relevant experiences from your background and prepare to showcase them during the interview.
    • Prepare questions: Consider any role-specific or team-related questions to ask your interviewer.
    Practice Questions:

  • This interview evaluates your problem-solving abilities through coding exercises that demonstrate the appropriate use of algorithms and data structures, as well as idiomatic choices in your programming language. The problems are generic and not tied to a specific technical domain. You are expected to write testable code and clearly identify what you would test.

    • Study algorithms: Research algorithms such as sorting, breadth-first search, depth-first search, binary search, and tree operations (insertion, deletion, and search).
    • Understand Big-O notation: Familiarize yourself with how Big-O is used to calculate time and space complexity.
    • Know your data structures: Familiarize yourself with the complexities for inserting, removing, and fetching elements in the data structures.
    • Practice problem-solving: Write and debug code regularly to become proficient. Prepare test scenarios, especially for exception cases.

Preguntas frecuentes

  • Your Recruiter can help you understand the target level for your interview. Different levels may have distinct interview processes. The Business Phone Screen determines the initial level you’re moving forward with, but the final level is decided after the interview panel's evaluation and debrief. Releveling may still occur at that stage based on performance and feedback.

  • Interviews are typically 60 minutes each, but your Recruiter will confirm the exact duration. While the format is generally consistent, there are nuances by domain, and your Recruiter will provide specific details about what to expect.

  • Puedes usar la IA para preparar tu entrevista, por ejemplo, para practicar las respuestas, investigar la función o estructurar tus respuestas. Sin embargo, no podrás usar herramientas de IA (por ejemplo, ChatGPT, generadores de respuesta automatizados, herramientas de autocompletado de código) durante la entrevista. Queremos evaluar tus habilidades, capacidad de resolución de problemas y proceso de pensamiento en tiempo real. Si tu entrevista incluye resolución de problemas técnicos o basados en casos, prepárate para explicar y justificar tus respuestas sin la ayuda de la IA.

  • Your Recruiter is working diligently to keep things moving. Typically, you can expect your Recruiter to follow up within 2-3 business days after each interview. However, timelines can shift, so if you haven’t heard back, don’t hesitate to reach out!

  • Después de tus entrevistas, recibirás una encuesta para compartir tus opiniones e ideas sobre la experiencia. Si no tienes noticias nuestras, no dudes en contactar a la persona que te reclutó.
