Google L3 Loop
Coding carries the L3 decision: interviewers look for correct, well-tested solutions explained clearly as you work. There is no system design round at this level. Committee approval usually leads to team matching, and some candidates who pass do not find a team right away.
The Rounds
Screens
- Recruiter ConversationsOne or two short calls on your background, the role, and location preferences.Practice Recruiter Conversations
- AssessmentsThe Google Hiring Assessment, and for some candidates a coding exercise, before interviews begin.Practice Assessments
- Technical Phone ScreenOne coding interview in a shared editor that does not run code. A second screen follows only when the first is inconclusive.Practice Technical Phone Screen
Onsite
- CodingTwo rounds of data structures and algorithms, usually one harder problem with follow-ups.Practice Coding
- Additional CodingOne or two more rounds in the same format, for three to four coding rounds in all.Practice Additional Coding
- Googleyness and LeadershipOne behavioral round of past-experience and hypothetical questions on collaboration, ownership, ambiguity, and learning from feedback.Practice Googleyness and Leadership
What the L3 Loop Weighs
- Clarify the problem and state an approach before writing code.
- Write complete, readable code without a compiler, then test it by hand on edge cases.
- Give time and space complexity for every solution, including the follow-ups.
- Bring a few concrete stories about teamwork, setbacks, and what you learned from them.
