Η ζώνη κινδύνου: Κορυφαίοι λόγοι που οι υποψήφιοι αποτυγχάνουν

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

  • Failing to handle sentence length differences appropriately (e.g., brevity penalty).
  • Failing to explain the rationale behind the refactoring choices.
  • Jumping to conclusions about the root cause without systematic investigation.
  • Not addressing caching strategies for frequently translated phrases or sentences.

  1. 2

    Τύπος · Algorithmic

    Given a large corpus of translated text pairs (e.g., English-German), design an algorithm to efficiently find the most frequent n-grams (sequences of n words) that appear in both languages, considering different sentence structures and word orders.
  2. 3

    Τύπος · Algorithmic

    Implement a function that takes a list of sentences and a dictionary of known phrases (e.g., idioms, technical terms) and returns a new list where known phrases are replaced by a special token, while preserving sentence structure and handling overlapping phrases.

  1. 4

    Τύπος · System Design

    Design a scalable system for DeepL's document translation feature. Consider aspects like handling various file formats (PDF, DOCX, etc.), preserving formatting, managing large file uploads, and ensuring translation quality across different document types.
  2. 5

    Τύπος · System Design

    How would you design a real-time translation API service that can handle millions of requests per day with low latency? Discuss the architecture, potential bottlenecks, and strategies for scaling.

  1. 6

    Τύπος · Debugging

    A user reports that translations for a specific technical domain (e.g., legal contracts) are consistently producing nonsensical output. The codebase involves multiple translation models and pre/post-processing steps. Debug this issue.
  2. 7

    Τύπος · Algorithmic

    Implement a function to evaluate the quality of a machine translation using a simplified metric similar to BLEU, but focusing on word overlap and sentence structure similarity. Handle edge cases like empty inputs or very short sentences.
