Structured Problem Solving – When faced with open-ended architecture or coding challenges, avoid jumping straight to a solution. First, clarify the requirements, outline your assumptions, discuss trade-offs, and then present a structured, step-by-step approach.

Code Quality & Detail – Whether in the take-home challenge or live coding sessions, your code must be clean, modular, and well-documented. Pay close attention to edge cases, error handling, and ease of deployment.

Collaborative Communication – Your interviewers want to see how you work as a teammate. Use active listening, explain your thought process clearly during whiteboarding sessions, and ask insightful questions about the team's current challenges.

The interview process for a DevOps Engineer at RealSelf is designed to evaluate your technical execution, architectural thinking, and cultural fit over several progressive stages. The loop is structured to ensure that candidates possess the practical skills required to manage their production environments immediately upon joining.

The process begins with an initial technical recruiter screen, followed by a take-home coding challenge with a strict completion window. Candidates who submit strong solutions are invited to a technical screen—often styled as a casual "coffee interview" or a virtual equivalent—where you will discuss your past projects and whiteboard architectural solutions. The final stage is a rigorous four-hour onsite loop containing deep-dive technical panels, system design sessions, and leadership interviews.

The timeline shown above outlines the standard progression from your initial application to the final decision. Candidates should use this visual guide to pace their preparation, ensuring they allocate sufficient time to practice coding before receiving the take-home challenge. While the overall process is structured, the timing between the final onsite and the offer stage can vary depending on team alignment and scheduling.

To pass the technical bar at RealSelf, you must perform exceptionally well across three core competencies. Each area is tested through a mix of practical challenges and deep-dive discussions.

Web-Scale Architecture & Performance

This evaluation area focuses on your ability to keep the RealSelf platform fast, reliable, and cost-efficient. You must demonstrate a deep understanding of how web requests flow from a user's browser down to the database layer.

Be ready to go over:

• Autoscaling Policies – How to configure target tracking, step scaling, and scheduled scaling for web servers and background workers.
• Caching Strategies – Implementing and managing Redis, Memcached, and CDN edge caching to reduce database load and improve page speeds.
• Database Scaling – Read replicas, connection pooling, and indexing strategies for relational databases under heavy read loads.
• Advanced concepts – Global load balancing, multi-region failover, and mitigating distributed denial-of-service (DDoS) attacks at the routing layer.

Example scenarios:

• "Our main web application is experiencing a sudden 3x spike in traffic, and database CPU usage is at 95%. Walk me through your immediate mitigation steps and your long-term architectural fix."
• "Design an autoscaling strategy for a containerized microservice that processes asynchronous image uploads."

Coding & Automation Engineering

You will be evaluated on your ability to write clean, maintainable automation code. RealSelf expects DevOps engineers to operate with a software engineering mindset, using code to eliminate manual operational tasks.

Be ready to go over:

• Scripting Proficiency – Writing robust scripts in languages like Python, Go, or Bash to automate infrastructure tasks.
• Input Validation & Edge Cases – Ensuring your code handles unexpected inputs, API rate limits, and network timeouts gracefully.
• Command-Line Interface (CLI) Design – Creating tools with clear flags, usage instructions, and clean output formatting.

Example scenarios:

• "Write a script that queries a cloud provider's API, identifies all unencrypted storage volumes, and sends an alert with the resource details."
• "Create a command-line tool that parses a configuration file and deploys a set of microservices in a specific order based on dependencies."

Infrastructure as Code & SRE Practices

This area assesses your familiarity with modern infrastructure management practices, focusing on reproducibility, monitoring, and continuous delivery.

Be ready to go over:

• Declarative Infrastructure – Writing modular, reusable Terraform or CloudFormation templates to manage cloud resources.
• CI/CD Pipelines – Designing automated pipelines that run tests, build container images, and deploy code safely to production.
• Observability – Setting up structured logging, metrics collection, and actionable alerting using tools like Datadog, Prometheus, or the ELK stack.

Example scenarios:

• "How do you manage state files and prevent race conditions when multiple engineers are modifying the same Terraform codebase?"
• "Describe how you would design a deployment pipeline that supports canary releases and automatic rollbacks based on error rates."

As a DevOps Engineer at RealSelf, your primary responsibility is to build and maintain the platform infrastructure that supports the core business. You will spend your days working on a mix of planned engineering projects and operational support.
