Interview Process

The interview consisted of multiple-choice questions focused on machine learning, followed by a hands-on coding assessment. The total duration was 70 minutes, which felt very tight.

Technical Questions

  • Machine Learning: Six multiple choice questions
  • Neural Networks: One question on calculating the sigmoid function
  • Coding Challenge: Given an expression such as 1639+5628, add parentheses to minimize the arithmetic result (e.g., 16(39+5)628). The candidate was required to explore all possibilities.
  • Decision Trees: A hands-on question related to decision trees.

Tips & Insights

Make sure to manage your time effectively, as the interview is quite fast-paced. Familiarize yourself with common algorithms and practice coding under time constraints.
