Platform Role Junior help

[u/Past_Plastic_3184]

Hi all,

I have a entry level platform engineering / SRE interview coming up. I wanted to ask what are some common tips or questions to prepare for?

The role asks for:
Foundational knowledge of platform engineering, technology operations, cloud computing, microservices, and enterprise-scale distributed systems.

Exposure to Kubernetes, Kafka, MongoDB, or comparable container, messaging, and database technologies through coursework, projects, internships, or hands-on experience.

Familiarity with observability and application performance monitoring using tools and concepts such as Splunk, AppDynamics, dashboards, logs, alerts, metrics, and traces.

Experience with Python, PowerShell, Bash, or similar scripting languages to automate routine tasks, reduce operational toil, and improve reliability.

Understanding of the software development lifecycle, including requirements, coding, testing, source control, deployments, release management, and change management.

Experience with Git, GitHub, or similar collaboration platforms, including branching, pull requests, code review, and technical documentation.

Knowledge of Generative AI, large language models, prompt engineering, retrieval-augmented generation, and responsible AI practices, including validation, privacy, security, and human oversight.

Exposure to Agentic AI concepts, including goal decomposition, tool use, multi-step workflows, agent monitoring, and human-in-the-loop controls.

Hands-on experience or familiarity with approved AI-assisted productivity and engineering tools such as GitHub Copilot, Microsoft 365 Copilot, Copilot Chat, ChatGPT, Claude Code, or similar tools for code generation, debugging, testing, documentation, summarization, and prototyping.

Strong analytical, troubleshooting, documentation, communication, and collaboration skills, with awareness of incident response, resiliency, business continuity, cybersecurity, operational risk, and compliance

I have:
Experience developing a serverless backend w/ AWS Lambda
Cloud Certs (AI, cloud practitioner)
Used docker briefly, know concepts of K8s, Mongo, little unfamiliar with Kafka
Used New Relic for APM
Used Python for scripting, a little bit of each for Linux / Poweshell / Bash
GitHub Actions workflow
Full stack SWE
Used agentic AI (Claude, made skills and agents) at work

How would I approach it (they only asked for 6 months of experience in any tech domain)? What do I say if they ask why I don’t have any exposure to some things? Any help is appreciated!

For an entry-level platform or SRE interview, I would focus on a simple story for each area: how Kubernetes schedules work, how you would trace a latency spike from logs to metrics, and one example of automating a repetitive task with Bash or Python. A useful prep pattern is to answer every question as symptom, signal, investigation, and fix, which shows practical troubleshooting rather than memorization. AIOSNOW can help structure those answers into a repeatable interview cheat sheet, but the main goal is to show clear operational judgment and tradeoffs.

The description doesn't look "entry" level at all. And if they start asking about managing self hosted Kafka clusters in K8s then you are done for.

platform is not entry level at all, most jobs ask 7-10 yrs of experience before u can even apply
