Google Early Career VO: Meeting Rooms II and Self-Describing Pi Indices

Role: Software Engineer, New Grad / Early Career
Result: Passed the virtual onsite
Report time: January 2026

The candidate reported two coding questions.

Coding 1: Meeting Rooms II

Given meeting intervals, return the minimum number of rooms needed so that every meeting can run without overlap.

Practice: Minimum Number of Chairs / Meeting Rooms II

Coding 2: self-describing positions in Pi

Pi is supplied as a digit string, such as [removed]. Return every one-based index i whose decimal digits match the digits of Pi beginning at that position.

For a multi-digit index such as 456, the match requires:

• pi[454] == '4'
• pi[455] == '5'
• pi[456] == '6'

Those zero-based accesses correspond to the one-based position beginning at 455 in the digit string.

Practice: Self-Describing Indices in Pi Digits
