Η ζώνη κινδύνου: Κορυφαίοι λόγοι που οι υποψήφιοι αποτυγχάνουν

Με βάση τη βάση δεδομένων μας με αποτελέσματα συνεντεύξεων n8n, αποφύγετε αυτές τις συνηθισμένες παγίδες:

  • Not applying the learned technology to a practical problem.
  • Incorrectly implementing Depth First Search (DFS) state tracking (e.g., not using three states: unvisited, visiting, visited).
  • Focusing only on persuasion without mentioning data or logical reasoning.
  • Focusing only on the n8n code and ignoring external factors.

Δοκιμάστε τον εαυτό σας: Πραγματικές ερωτήσεις n8n

Τρία πραγματικά prompts τραβηγμένα από τη βάση δεδομένων μας.

Τύπος · Influence

Describe a situation where you had to influence a stakeholder (e.g., engineer, designer, executive) who had a different opinion or priority. How did you approach it, and what was the result?

Τύπος · String Manipulation

Implement a function that takes a string representing a user's input for a webhook URL and sanitizes it. It should remove any potentially harmful characters, ensure it starts with 'http://' or 'https://', and replace common placeholders like '{currentNodeId}' with a generic placeholder like '[ID]'.

Τύπος · API Design

Design the API for n8n's internal service that manages user credentials for various third-party integrations. Consider authentication, authorization, encryption, and rate limiting.

  1. 1

    Τύπος · Motivation

    What interests you about n8n specifically, and how do you see your skills contributing to our mission of empowering everyone to automate workflows?
2

Coding Screen

3
  1. 2

    Τύπος · Algorithmic

    Given a list of n8n workflow execution logs, where each log entry contains a timestamp and a status (e.g., 'success', 'failed', 'running'), write a function to find the longest consecutive period where no workflow execution failed.
  2. 3

    Τύπος · Data Manipulation

    n8n allows users to connect to various services. Imagine you have a JSON object representing a webhook payload from a third-party service. Write a function to deeply flatten this JSON object, where keys are concatenated with a delimiter (e.g., '.'). For example, {'a': {'b': 1}} becomes {'a.b': 1}.

  2. 5

    Τύπος · Scalability

    n8n's workflow execution can sometimes involve long-running tasks or a high volume of concurrent executions. How would you design a system to handle potentially millions of concurrent workflow runs efficiently, ensuring reliability and fault tolerance?

  1. 6

    Τύπος · Algorithmic

    Implement a function to detect cycles in a directed graph representing n8n workflow dependencies. If a cycle is detected, return the nodes involved in the cycle. This is crucial for preventing infinite loops in complex workflows.
  2. 7

    Τύπος · Debugging

    A user reports that their n8n workflow occasionally fails with a 'timeout' error when calling a specific third-party API. The workflow uses a custom HTTP Request node. Debug this issue. What steps would you take, what tools might you use, and what are potential root causes?

    Τύπος · Ownership

    Tell me about a time you took ownership of a project or problem that was outside your direct responsibility. What was the situation, what did you do, and what was the outcome?
  2. 9

    Τύπος · Influence

    Describe a situation where you had to influence a stakeholder (e.g., engineer, designer, executive) who had a different opinion or priority. How did you approach it, and what was the result?
