What Google says about its process
- 1Google evaluates each application against the qualifications and responsibilities of the specific role, so the exact interview sequence and technical emphasis vary by team and level.
- 2Official interview guidance encourages candidates to understand the role, prepare concrete examples, and treat technical conversations as collaborative problem solving.
- 3Software engineering roles commonly require data structures, algorithms, software development, testing, and—at more experienced levels—design and architecture skills.
- 4Candidates should make assumptions explicit, communicate their reasoning, test their work, and use the preparation instructions supplied by the recruiting team as the source of truth.
