Interview Process
The interview consisted of multiple rounds focusing on string and array manipulation problems. Each round involved solving problems on a whiteboard and discussing the thought process behind the solutions.
Technical Questions
-
Stock Car Race Elimination
Given a two-dimensional string array with each driver’s name and lap time in seconds, return the drivers in the order in which they were eliminated. The elimination is based on the slowest “best” time, and names should be listed alphabetically if tied. -
User-Generated Content Reporting
Analyze an array of user messages to count how many messages have an odd length and contain at least one vowel (both uppercase and lowercase).
Tips & Insights
- Focus on understanding the problem requirements clearly before jumping into coding.
- Practice string manipulation and array handling problems to build confidence.
- Discuss your thought process clearly during the interview to demonstrate problem-solving skills.
