The Sea Limited DNA (TL;DR)

Sea's core principle 'We Run' defines an interview loop focused on execution velocity and high-concurrency architecture across Shopee and SeaMoney platforms. Interviewers rigorously test whether candidates can scale systems under extreme flash-sale traffic bursts.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Sea Limited interview outcomes, avoid these common traps:

  • Giving a generic answer that could apply to any tech company.
  • Not designing for fan-out to millions of users efficiently.
  • Not demonstrating an understanding of Sea's diverse business units.
  • Not discussing the trade-offs between accuracy and performance of the rate limiting algorithm.

Imagine you are building a recommendation system for Garena's games. Given a user's past game plays (list of game IDs and duration) and a list of available games with their genres and popularity scores, write a function to recommend the top 3 games a user might like, based on genre similarity and popularity. Prioritize games with genres similar to those the user plays most often.

Type · design

CIRCLES
Design a system to handle real-time inventory updates for Shopee. Millions of products are listed, and inventory levels change frequently due to sales, returns, and stock replenishment. The system must ensure accuracy and minimize discrepancies between the displayed stock count and the actual stock.

Type · collaboration
