I recently went through the Google SWE II (Early Careers) loop and documented the full experience — all 4 rounds with the topics asked, what went well, and what didn't.

Quick summary:

Round 1 (Trie + HashMap) — Strong Hire
Round 2 (Graphs + DSU modification) — Strong Hire
Round 3 (DP + Binary Search optimization) — Hire
Round 4 (Googliness + DSA) — Lean Hire
Currently in team matching.

I wrote a detailed breakdown here with tips for each round:

Also started documenting the actual questions asked (with constraints, examples, and follow-ups that interviewers asked):

- https://beyondleet.dev/questions/trie-hashmap-string-matching
- https://beyondleet.dev/questions/modified-union-find-graph-components
- https://beyondleet.dev/questions/dp-to-binary-search-optimization

Hope this helps anyone preparing for Google. Happy to answer questions.
