SRE Interview Prep Plan (Week 6)
Series Overview:
Week 1: Fundamentals of SRE
Week 2: Automation & Scripting
Week 4: Incident Management Lifecycle
Week 6: Mock Interviews and Revision (This post)
As we step into the final week of our SRE interview preparation plan, it's time to focus and polish our skills.
Week 6 is designed to simulate the real interview experience, combining technical and behavioral mock interviews with a focused revision period. Through technical mock interviews on Days 1-3, our focus would be to sharpen our problem-solving and communication skills.
Days 6-7 offers a critical opportunity for revision and personalized feedback, allowing you to refine your approach and improve your understanding based on the insights gained. This final push is about more than just acing your interviews; it's about laying a solid foundation for a thriving career in Site Reliability Engineering.
🚀 For the mocking interviews you can use ChatGPT or any other suitable AI chat bot. If you want to go through a more authentic experience with a real person you can look for services that provide it as a paid service, e.g. https://interviewing.io/ (not sponsored)
Days 1-3: Technical Mock Interviews
Day 1-2: LeetCode Coding Challenges
The first day kicks off with a deep dive into LeetCode problems, focusing primarily on data structures and algorithms. Your tasks for the day will include a balanced mix of easy to medium difficulty questions, covering arrays, linked lists, and binary trees. If you know you will be interviewing for a more dev focused roles throw in some hard challenges as well. You should approach problems methodically, emphasizing not just the correctness of your solutions but also their efficiency and scalability. Talk the solutions out loud to illustrate your train of thought, because that's what interviewers would expect from you. After completing the challenges, spend some time reviewing your solutions, identifying areas for optimization and alternative approaches.
Day 3: System Design Fundamentals
Transitioning from coding challenges, spend Day 3 on System Design problems, a critical component of the SRE interview process. You should already be confident with it, but find some scenarios that require you to design scalable, reliable, and efficient systems, reflecting real-world problems SREs often face. Start with fundamental concepts such as load balancing, caching, and database selection, moving towards designing a complete system by the end of the day. Ensure you consider scalability, resilience, and maintenance, and not just the immediate requirements. Engage in mock interviews where you'll need to explain your design choices, trade-offs, and how you'd monitor and troubleshoot the systems you design.

These three days of intensive technical mock interviews are structured to cover a broad spectrum of topics and question types you're likely to encounter.
Remember, the goal is not just to find the right answers but to demonstrate clear, logical thinking, and effective communication of complex ideas.
Days 4-5: Behavioral Mock Interviews Focusing on SRE Scenarios
Day 4: Behavioral Interview Fundamentals
The fourth day of the week shifts the focus towards behavioral aspects, crucial for any SRE role. This day explore your past experiences, focusing on scenarios that highlight your problem-solving skills, teamwork, leadership, and resilience. The STAR method (Situation, Task, Action, Result) will be your guiding principle, helping you structure your responses in a clear, concise, and compelling manner. Ask yourself questions like, "Describe a time when you had to troubleshoot a critical issue under tight deadlines," or "Tell us about a moment when you proposed a change that significantly improved system reliability." The aim is to not just recount your experiences but to demonstrate your thought process, decision-making skills, and the impact of your actions.
Day 5: Incident Management and Collaborative Problem-Solving
Building on the behavioral foundations, Day 5 goes into SRE-specific scenarios, particularly focusing on incident management, system failures, and collaborative problem-solving under pressure. You'll face questions designed to uncover your ability to manage crises, coordinate with cross-functional teams, and communicate effectively during high-stakes situations. Prepare for questions like, "Explain how you managed a major service outage," or "Describe your approach to resolving a conflict within your team during a critical system update." Utilizing the STAR method, your responses should clearly articulate how you identified the issue, formulated a strategy, collaborated with others, and implemented a solution that mitigated the impact of the incident.
Resources:
These two days of behavioral mock interviews are crucial for demonstrating your soft skills, which are as important as your technical skills in an SRE role. Employers look for candidates who not only have the technical expertise to manage and improve systems but also the interpersonal skills to work effectively within teams and handle stress and conflict gracefully.
Days 6-7: Revision and Feedback
Day 6: Comprehensive Revision
On Day 6, it's time to consolidate your learnings from the week. Begin with a thorough review of the technical concepts and system design principles you tackled in the first three days. Revisit the LeetCode problems and system design scenarios, paying special attention to the areas where you felt challenged or received constructive feedback. This is also a good opportunity to refine your understanding of SRE fundamentals, including reliability patterns, performance metrics, and incident management protocols. Use this day for focused study sessions, perhaps revisiting key resources or tutorials that address your areas for improvement. The goal is to reinforce your knowledge base and sharpen your skills, ensuring you're well-prepared for any technical question that might come your way.
Day 7: Reflecting on Feedback and Setting Goals
The final day of your interview preparation plan is dedicated to reflection and forward planning. Start by reviewing the feedback received during your mock interviews. Identify common themes or areas for improvement, whether they relate to technical skills, communication, problem-solving approaches, or behavioral responses. Reflect on this feedback critically, acknowledging your strengths and recognizing areas where you can grow.
After this reflection, set actionable goals for continued improvement. These might include continue mastering specific technical skills, practicing the STAR method to refine your storytelling abilities, or engaging in more real-world problem-solving exercises to build your confidence and competence in SRE scenarios. Consider scheduling follow-up mock interviews with peers or mentors to assess your progress against these goals.
Additionally, use this day to practice self-care and mental preparation. Interviewing can be stressful, and ensuring you're mentally and physically ready is as important as the technical and behavioral preparation.
Days 6 and 7 wrap up your intensive interview preparation plan by emphasizing the importance of self-assessment and continuous improvement. By taking the time to review, reflect, and set future goals, you're not just preparing to succeed in your interviews but also laying the groundwork for a thriving career.
Conclusion
As we conclude our six-week SRE interview preparation journey, remember that the essence of success lies in the balance between both technical and behavioral proficiency.
🚀 Stay committed to continuous learning, and approach your interviews with confidence. Don't stop practicing preparation topics while you are hunting for jobs, talking to recruiters and engineering managers. Good luck!
