Checked 3 August 2026. Google states that a committee decides and names the four attributes it scores. Round counts and timeline are commonly reported by candidates, not published. Source: careers.google.com/how-we-hire.
| Round | Duration | What it tests |
|---|---|---|
| Phone Screen | 45 min | Light coding or strategy conversation. |
| Coding Round | 45 min | One hard problem. Approach matters more than completion. |
| System Design (Deep) | 90 min | 90-minute design with multi-year strategy implications. |
| Cross-Org Strategy | 60 min | Technical strategy across an org. |
| Googleyness and Leadership (Org Scope) | 60 min | Company-level impact, hiring, strategy. |
| VP / Director Round | 45 min | Vision, fit, leadership style. |
Targeted guidance per round in this loop. Each section links to the matching track on the site. There is no shortcut list, the bar moves loop to loop, so build the pattern recognition and the stories from real practice.
Work the pattern templates until the recognition is instant. Trace one mock problem per pattern. Practice stating time and space complexity out loud before you write code.
Google L7 (Senior Staff Software Engineer) has one design round: System Design (Deep) (90 min): 90-minute design with multi-year strategy implications.. Bar is multi-year architectural bets and cross-org technical strategy. You should be naming specific decisions you would defend in a roomful of senior engineers. Pick problems from the track at the scale this loop tests and rehearse the structure: requirements, numbers, high-level design, data model, API, deep dive on one part, trade-offs.
Principal bar. Multi-year bets, executive-level communication, cross-org influence, and growing Staff engineers. The behavioral rounds often outweigh technical-depth rounds in the final hiring decision at this level. Googleyness (humility, conscientiousness, comfort with ambiguity) is the framework to map stories to.
