DevOps Engineer Behavioral medium

Describe a blameless post-mortem you led. How did you ensure actionable takeaways without pointing fingers?

#Incident Management #Post-mortems #Culture #Continuous Improvement
DevOps Engineer Behavioral medium

Spotify values 'fail fast, learn faster.' Tell me about a time a deployment you managed failed spectacularly in production. What did you learn?

#Failure #Learning #Resilience #Accountability

DevOps Engineer Behavioral medium

Tell me about a time you had to collaborate with a cross-functional team (engineers, product, data) to resolve a complex infrastructure issue.

#Collaboration #Cross-functional #Communication
DevOps Engineer Behavioral hard

Describe a situation where a critical production incident was caused by a gap in your monitoring. How did you handle the incident and the aftermath?

#Incident Management #Observability #Continuous Improvement
DevOps Engineer Behavioral medium

Spotify operates on a model of high alignment, high autonomy. How do you ensure security and compliance standards are met without bottlenecking autonomous squads?

Write a Bash script to check the HTTP status code of a list of Spotify API endpoints from a file and alert via Slack webhook if any return 5xx.

#Bash #cURL #Monitoring #Automation
DevOps Engineer Coding medium

Write a Go program that concurrently pings a set of internal services and reports their latency percentiles (p50, p90, p99).

#Go #Concurrency #Goroutines #Math/Statistics
DevOps Engineer Coding hard

Implement a custom Kubernetes controller in Go that automatically labels pods with their respective Spotify squad owner based on a central metadata registry.

#Go #Kubernetes API #Controllers #Automation

Write a Dockerfile for a Node.js application that follows security best practices.

#Docker #Security #Node.js
DevOps Engineer Coding medium

Write a script that parses a Terraform plan JSON output and fails the CI build if any IAM policies are being modified to allow public access.

#Terraform #JSON #Security #CI/CD

How would you architect a disaster recovery strategy for Spotify's user metadata database (e.g., saved songs, followers) across multiple GCP regions?

#Disaster Recovery #GCP #Databases #High Availability
DevOps Engineer System Design medium

Design an observability pipeline that ingests millions of log lines per second from Spotify clients and backend services.

#Observability #Data Pipelines #Kafka #Elasticsearch
DevOps Engineer System Design hard

Design a system to securely distribute and rotate TLS certificates for thousands of internal microservices without service interruption.

#Security #TLS #Automation #PKI
DevOps Engineer System Design medium

Design an automated rollback mechanism for a CI/CD pipeline when a canary deployment exhibits an elevated error rate.

DevOps Engineer Technical medium

How do you handle secrets management in a multi-cluster Kubernetes environment on GCP, specifically for autonomous squads?

#Kubernetes #GCP #Secrets Management #Security
DevOps Engineer Technical hard

Spotify uses Backstage extensively. How would you design a CI/CD pipeline template in Backstage that standardizes deployments but allows squads flexibility?

#Backstage #Developer Experience #CI/CD #Standardization
DevOps Engineer Technical medium

Explain how you would implement zero-downtime deployments for a stateful microservice handling user playlists.

#Kubernetes #StatefulSets #Zero-Downtime #Database Migrations
DevOps Engineer Technical easy

What is the difference between a Kubernetes Deployment and a StatefulSet? When would you use each in a streaming platform?

#Kubernetes #Deployments #StatefulSets
DevOps Engineer Technical hard

How do you manage Terraform state files for hundreds of microservices managed by dozens of different squads?

#Terraform #State Management #Collaboration #GCP
DevOps Engineer Technical medium

Walk me through how you would troubleshoot a sudden spike in 502 Bad Gateway errors in a GKE cluster.

#Kubernetes #GKE #Networking #Debugging
DevOps Engineer Technical medium

Explain the concept of GitOps. How would you implement it using ArgoCD for a fleet of Kubernetes clusters?
