Summary

  • Published 2026-03-03 · slug moloco-ml-codesignal-2026 · category "Hiring, interviews, and careers / Online coding-test retrospectives" · source article recorded in Korean and English.
  • A retrospective on the MOLOCO ML Engineer Intern CodeSignal assessment, which I passed to reach the interview stage. On 2026-09-24, the article was rewritten around preparation and lessons learned, removing test questions and solutions because assessment rules prohibit disclosure.
  • Main lesson: use a decision-criteria table to move quickly through conceptual multiple-choice questions and reserve time for implementation. Ties, empty groups, and return formats were the edge cases that separated results.
  • Follow-up: MOLOCO ML Engineer Intern: Screening Interview.

Mentioned

  • Moloco: the prospective employer, styled MOLOCO in the blog.
