The Google interview process
Recruiter screen -> technical phone screen -> 4-5 onsite rounds (coding, system design for senior, Googleyness & leadership) -> hiring committee
The actual Google interview loop
Highly standardized loop where interviewers submit written feedback and a separate Hiring Committee (not the interviewers) makes the final call; strong emphasis on General Cognitive Ability and clean, optimal code in a shared doc or Google's browser-based interview coding editor.

~30 min · EasyBackground, level calibration, and process walkthrough with a recruiter.
resume walkthrough · role fit · process expectations

arrays and strings · hashmaps · recursion · time-space complexity
3. Coding round (onsite)
~45 min · HardHarder DSA with follow-up constraint changes; interviewer scores GCA and RRK on a rubric.
graphs · dynamic programming · trees · edge-case handling
4. System design round
~45 min · HardDesign a planet-scale system (e.g. a piece of Search or YouTube) with explicit capacity estimates and tradeoffs.
