Interview Process

The interview process consisted of an online assessment (OA) followed by a telephonic interview. The OA included four algorithm questions, lasting a total of 70 minutes with the camera on. There was no specific score given at the end. The telephonic interview included a personality test that lasted 40 minutes, featuring multiple choice questions related to the job, which did not require the camera to be turned on.

Technical Questions

  1. Algorithm: Given a number, return a modified sequence based on its digits. For example, for num = 1245, return 1-2+4-5. For num = 2346, return 2-3+4-6. A brute force approach is sufficient to pass all tests.
  2. List: Find the highest point in a list one at a time, remove it gradually, and return the sequence of removals. A brute force approach is sufficient to pass all tests.
  3. Matrix: Return the regional average of a given matrix.
  4. Abstract Problem: Given two lists x and y of the same length, determine how many of the following equations are satisfied: x[0]-y[0], x[0]-y[1], x[1]-y[0], x[1]-y[1]. Return 1 if one equation is satisfied, 2 if two are satisfied, and 3 if all three are satisfied. A brute force approach can pass the first 10 examples, but later examples may timeout.

Tips & Insights

  • Familiarize yourself with algorithmic problem-solving techniques, particularly brute force methods, as they can often help in passing initial tests.
  • Practice solving problems under time constraints to improve speed and efficiency.
