About

Not the focus of the interview, but part of the job. Teams ask about these, so be ready to talk about them:

• Git, branching and code review as a daily habit
• One cloud provider used in anger: AWS, Azure or GCP
• CI/CD: your work reaches an environment without somebody carrying it
• Docker, and a container platform in production: Kubernetes, ECS or equivalent
• SQL beyond CRUD: indexes, query plans, and why a join got slow
• A queue or stream (Kafka, SQS, RabbitMQ), and what you do when it backs up
• Logs, metrics and traces you actually read when something is on fire
  
  

How The Interview Goes

Expect to be asked how you would approach a problem in each of the areas above, and why you would not take the obvious route. Then one level down on whichever answer was weakest.
