Interview Process
The interview consisted of multiple rounds, including technical and problem-solving assessments. The format was primarily virtual, with coding challenges shared via an online collaborative platform. Each round lasted approximately 45 minutes to an hour, focusing on algorithmic thinking and coding skills.
Technical Questions
- Card Sorting Problem: Given a deck of cards numbered from 1 to n, determine the minimum number of cards k that need to be moved from the deck to arrange the deck in ascending order using shuffle moves. If it’s impossible to sort the deck, return -1.
- Missing Number in 4x4 Squares: You are given a matrix containing multiple 4x4 squares with numbers from 1 to 16, except for one missing number represented by “?”. Your task is to find the missing number, replace it, and rearrange the squares in ascending order based on their missing values.
Tips & Insights
- Focus on understanding the problem requirements clearly before jumping into coding.
- Practice common algorithms and data structures beforehand, as they often come up in interviews.
- Communicate your thought process clearly during the interview to demonstrate your problem-solving approach.
