Stage 4

4. Technical Screen 3 + Leadership Round (Architecture, business impact, culture fit)

🎯 Breakdown of Interview Rounds

1. High-Concurrency Architecture

Designing systems that handle millions of video streams per second with distributed Redis, Kafka, and sharded storage.

2. Recommendation Algorithms & Deep Learning

Two-tower recommendation models, real-time feature stores, embedding search (FAISS/Milvus), and ranking models.

❓ Real ByteDance Interview Questions & Hints

Question 1 • System Architecture

“How would you design the video feed recommendation caching layer for TikTok to handle 100 million active users globally?”

💡 Recruiter Hint & Strategy:Discuss multi-tiered caching, feed pre-generation, consistent hashing, and edge CDN distribution.

⭐ Model Answer Structure:We employ a two-tiered architecture: candidate generation (coarse retrieval) using approximate nearest neighbors on embeddings, followed by deep neural ranking models. User feeds are pre-cached in distributed Redis clusters sharded by user_id with consistent hashing, serving video chunks directly from regional edge CDNs.

🤖 ATS Resume Compatibility Tips

ByteDance uses an internal ATS. High LeetCode fluency, Go, Python, C++, Kubernetes, and large-scale distributed systems experience are mandatory.
