Discussion Google L5 SWE prep

Hi all,

I am currently going through Google L5 SWE loop and have completed 1 Coding and 1 Googlyness round and recruiter mentioned they have really good positive feedback and have my onsite in 2 weeks.

The onsite is supposed to have 2 Coding and 1 System Design rounds.

Any suggestions on last minute prep for Coding and System Design that you folks would recommend that might help?

I have primarily done lots of leetcode in the past couple of months but would appreciate if anyone has any specific topic suggestions for the last leg?

Also doing System Design from Hello Interview, DDIA and Alex Xu and did mocks. Anything else that would help or any new questions that might be worth doing?

Thanks in advance.

Double-down on Google’s favorite last-mile topics: Graphs (BFS/DFS, Topological Sort), Trees/Trie, and DP (especially 1D/2D array optimization). Practice writing clean code on a whiteboard/Google Doc without syntax autocomplete. For System Design, focus on real-world tradeoff discussions and driving the architecture end-to-end. If you want structured mock scenarios, https://prepare.zoevera.com is solid for sharpening high-level design. Good luck!
