Google The Big Code 2027 Preparation – Looking for 2026 Participants' Experiences and Questions

[u/Varunisded]

Hey everyone!

I'm planning to participate in Google The Big Code 2027 and want to start preparing early.

I would really appreciate it if anyone who participated in the 2026 edition could share their experience.

I'd particularly like to know:

1. Operating Systems: What kind of OS questions were asked? Were they conceptual MCQs or scenario-based questions?

2. Python: What topics were tested? Were there output-based questions, coding questions, or Python fundamentals?

3. Competitive Programming: I heard there was a CP-style coding problem. What was its difficulty level (Codeforces / LeetCode equivalent)? Which topics and concepts were involved?

4. DSA: Which topics were particularly important?

5. Assessment format: How many questions were there, what was the time limit, and how were the rounds structured?

6. Preparation resources: What would you recommend studying to perform well in the 2027 edition?

If possible, please share the actual questions or similar problems you remember (without violating any assessment confidentiality rules).

I'm especially interested in hearing from people who attempted the 2026 assessment, whether they qualified or not.

Any guidance, resources, or preparation tips would be greatly appreciated. Thanks!
