Infrastructure and Cloud Architecture
This area evaluates your ability to design, deploy, and manage large-scale distributed systems. Airbnb relies heavily on AWS, and your interviewers will expect you to understand the nuances of cloud networking, compute, and storage. You must demonstrate how to build systems that are highly available, secure, and cost-effective.
Be ready to go over:
- Infrastructure as Code (IaC) – Deep knowledge of Terraform, managing state files, and writing reusable modules.
- Containerization and Orchestration – Docker internals, Kubernetes architecture, writing deployment manifests, and understanding pods, nodes, and control planes.
- Cloud Networking – VPCs, subnets, routing tables, load balancers (ALB/NLB), and handling cross-region traffic.
- Advanced concepts (less common) – Service meshes (like Istio), eBPF for observability, and advanced AWS IAM policy debugging.
Example questions or scenarios:
- "Design a highly available multi-region architecture for a new internal service on AWS."
- "How would you structure a Terraform repository for a company with hundreds of microservices and multiple environments?"
- "Explain how a Kubernetes pod gets an IP address and how it communicates with a pod on a different node."
Linux Systems and Troubleshooting
When things break at Airbnb, the DevOps Engineer is often the first line of defense. This evaluation area tests your deep understanding of Linux internals, networking protocols, and systematic debugging. Interviewers want to see a logical, step-by-step approach to isolating faults.
Be ready to go over:
- Linux Internals – CPU scheduling, memory management (OOM killer), file systems, and inodes.
- Networking Protocols – TCP/IP handshake, DNS resolution, HTTP/HTTPS, and TLS termination.
- Observability and Monitoring – Using tools like Prometheus, Grafana, or Datadog to define SLIs, SLOs, and SLAs.
- Advanced concepts (less common) – Kernel tuning, debugging system calls with
strace, and analyzing TCP dumps.
Example questions or scenarios:
- "A developer reports that their application cannot connect to the database. Walk me through your troubleshooting steps."
- "What happens exactly when you type
curl https://www.airbnb.com and press enter?"
- "How would you investigate a server that is experiencing high load but low CPU utilization?"
Core Values and Behavioral Fit
Airbnb is famous for its culture, and the behavioral interviews are heavily weighted. Interviewers will assess your past experiences to see if you embody traits like "Be a Host" and "Embrace the Adventure." They want to ensure you are collaborative, empathetic, and capable of navigating ambiguity without ego.
Be ready to go over:
- Cross-functional Collaboration – How you work with software engineers to improve their workflows and adopt new tooling.
- Handling Failure – Discussing past outages you caused or mitigated, focusing on the post-mortem process and what you learned.
- Mentorship and Leadership – How you upskill your teammates and advocate for reliability best practices.
- Advanced concepts (less common) – Influencing product roadmaps to prioritize technical debt and infrastructure scaling.
Example questions or scenarios:
- "Tell me about a time you had to push back on a development team that wanted to deploy an unstable feature."
- "Describe a situation where you had to learn a completely new technology under a tight deadline."
- "Tell me about a time you went above and beyond to help a colleague succeed."
