Hey everyone,

I recently received the new Amazon SDE Online Assessment, and it looks like the format has changed quite a bit:

• Coding Challenge (100 min) – 2 questions (one standard DSA and one in a repository environment with an AI coding assistant)
• Work Simulation (~15 min)
• Work Style Surveys (~10 min)

I was wondering if anyone has experience with this new format and, specifically, whether anyone has tried using Cluely during the OA.

Hey everyone,

I recently got the Amazon SDE Online Assessment and noticed the format looks different from the usual OA. I wanted to check if anyone who recently gave it can share their experience.

From what I see, it includes 3 sections:

1. Coding Challenge (100 minutes)

• 2 coding questions
• One standard DSA problem
• One problem in a repo-based environment with an AI coding assistant

2. Work Simulation (~15 minutes)

• Scenario-based SDE situations
• Focus on decision-making + Amazon Leadership Principles

3. Work Style Survey (~10 minutes)

• Behavioral preference questions
• No coding, just work style alignment

I’m especially curious about:

• How the AI-assisted coding repo question actually works in practice
• Difficulty compared to the classic Amazon OA
• Whether the work simulation is similar to previous LP-based questions
• Any tips or things to expect for this new format

Would really appreciate any recent experiences or insights from people who have taken it 🙏

I have a Round 1 HackerRank + video interview coming up for the Software Engineer, C/C++ SDK Performance Optimization role at TikTok (San Jose), and I was wondering if anyone has gone through this interview process recently.

The role focuses on:

• C/C++
• SDK performance optimization
• Mobile performance (CPU/GPU/Memory)
• Camera/effect/rendering pipeline
• Cross-platform native development (iOS/Android)

For those who've interviewed for this role (or a similar Multimedia/Effect SDK/Rendering/Performance role at TikTok or ByteDance), I'd really appreciate any insights on:

1. What was Round 1 like?
2. Was it purely LeetCode/HackerRank, or were there C++ conceptual questions as well?
3. What difficulty were the coding questions (Medium/Hard)?
4. Were there follow-up optimization questions after coding?
5. Which DSA topics came up most frequently?
6. Did they ask about multithreading, memory management, STL, or modern C++?
7. How much emphasis was placed on graphics/rendering topics in the first round?
8. Any tips for preparing over the next few days?

Even if you've interviewed for another TikTok backend or systems role recently, I'd love to hear how your first technical round was structured.

Thanks in advance!
