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 (Coding) | 45 min | One medium with follow-up. |
| Coding Round 1 | 45 min | Algorithm or data structure. |
| Coding Round 2 | 45 min | Different problem space. |
| System Design (Light) | 45 min | Conversational design with basic depth. |
| Googleyness and Leadership | 45 min | Six attributes with feature-ownership stories. |
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 L4 (Software Engineer, Mid) has one design round: System Design (Light) (45 min): Conversational design with basic depth.. Bar is owning architectural direction across teams. Trade-offs need numbers, alternatives need names, and the deep dive should be in your strongest area. 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.
Staff bar. The work shifts to cross-team initiative, strategic judgment, influence without authority, and growing other engineers. Behavioral weight is roughly equal to system design at this level. Googleyness (humility, conscientiousness, comfort with ambiguity) is the framework to map stories to.
