Interview Process

The interview consisted of multiple coding rounds and discussions related to machine learning. The first coding round involved a problem where the candidate had to round a string representation of a number to the last significant digit. The second round focused on user action sequence modeling in a machine learning context, followed by a discussion on designing a related pins page.

Technical Questions

  • Coding Question: Given a string representation of a number (possibly with a decimal point), round to the last significant digit. (Example: 14.5 → 15.0, 150 → 200)
  • Machine Learning Question: Discuss user action sequence modeling.
  • Design Question: Design a related pins page.

Tips & Insights

  • Focus on understanding the problem requirements clearly before jumping into coding.
  • Be prepared to discuss design choices and the reasoning behind them during system design questions.
