Google New Grad R1: Worker-Efficiency Binary Search and Behavioral Interview

Role: Software Engineer, New Grad
Result: Passed R1
Report time: January 2026

Coding interview

The technical round used binary search and asked for the minimum number of workers needed to reach the highest efficiency.

The source does not define the worker inputs, how efficiency is calculated, the target condition, or what the minimum worker count must achieve. Because those missing rules determine the problem itself, no exact practice question is linked.

Behavioral interview

Questions focused on:

• Working through ambiguity
• Meeting a tight deadline
• Conflict between teammates
• Conflict with a senior colleague
• A past project

The candidate described the questions as standard for Google Early Career interviews.
