This is the most comprehensive, up-to-date Google SRE interview questions and preparation guide for 2026. If you're searching for a structured approach to the SRE troubleshooting round, NALSD, or Linux internals questions, this guide consolidates everything into one clear framework. The internet is filled with:
But none provide a structured, end-to-end system tailored to Google’s real interview expectations.
This guide fixes that.
After studying hundreds of Google SRE interview experiences, reverse-engineering evaluation patterns, and mapping the SRE job ladder, this guide compiles everything into one clear preparation framework.
Key Insights from This Guide:
- Google now tests for "Reliability Architects," not just firefighters.
- Linux Internals & NALSD (Non-Abstract Large Systems Design) are the new gatekeeper rounds that separate senior candidates.
- Success depends on structured reasoning and a "reliability mindset," not just memorizing commands.
- This guide provides a complete 30-day roadmap to master these modern concepts.
Google’s SRE interviews are not SWE interviews with “some Linux questions.”
They evaluate three core dimensions:
Can you think in failure modes, tradeoffs, and system risk reduction?
Linux internals, performance debugging, network reasoning, storage, kernel behavior.
NALSD (Non-Abstract Large Systems Design)
Troubleshooting
Scenario analysis
SLO-based thinking
This is why many experienced engineers fail Google SRE rounds — not due to lack of knowledge, but lack of structured preparation.
Google adjusts SRE interviews by role level, but this structure remains consistent:
Languages allowed: Python, Go, C++
Focus areas:
You debug issues like:
They don’t want commands — they want reasoning flow.
Google interviewers consistently reward candidates who follow a structured diagnostic model.
Here is the distilled framework:
Symptom →
Triage →
Assess →
Root Cause →
(M)itigation
NALSD is not standard system design.
It focuses on:
Example prompts:
“Design a system to safely deploy configuration changes globally with rollback guarantees.”
“How do you design a multi-region service with 99.99% availability without over-provisioning?”
The evaluation is not correctness — it’s judgment.
Many SRE candidates underestimate this section.
Google deeply tests:
This is where most candidates lose the interview — the gap between “basic Linux commands” and “systems-level reasoning.”
Below are actual reconstruction-style patterns Google tends to ask:
Signal Tested: Differentiating between application, system, and kernel-level bottlenecks under pressure.
- GC pauses?
- Thread pool exhaustion?
- BPF shows syscall latency?
- Disk IOPS throttling?
Signal Tested: Your ability to reason about blast-radius control and stateful workloads during a crisis.
- How to rebalance traffic?
- Stateful workload concerns?
- Capacity tradeoffs?
- Blast radius control?
Signal Tested: Awareness that not all outages are internal; reasoning about global internet infrastructure.
- How does global routing propagate?
- What mitigations reduce exposure?
Signal Tested: Thinking systemically about automation, not just fixing the immediate technical problem.
- Why monitoring missed it?
- Why alert routing failed?
- How to build a self-healing certificate layer?
These are not the scenarios you’ll find in books — they are the ones Google actually tests.
This roadmap is modeled on real interview success stories.
By the end of 30 days, your preparation becomes structured, predictable, and aligned with Google’s evaluation rubrics.
Because a lot of engineers asked for clarity, we created a full end-to-end Google SRE interview system:

Loose papers can ruin a first impression, but a well-arranged resume folder can instantly create a sense of confidence. When a professional carries their documents in a clean and organised way, it shows they are serious about the opportunity in front of them. In today’s competitive world, even small details matter, and document presentation is one of them.
A resume folder helps keep resumes, certificates, and important papers neat and protected. It works better than a basic file folder or paper folder because it looks more professional and supports a cleaner presentation. For many working individuals, the right resume file folder feels like a part of their identity—something that boosts their confidence during interviews and meetings.
A resume folder gives a clear message about the person holding it. It shows seriousness, discipline, and a responsible attitude. When someone walks into an interview with a proper folder or folder file instead of loose documents, it sends a strong signal of professionalism. Recruiters often notice these small details.
It also reflects good organisational skills. A professional who uses a professional resume folder shows that they take their work seriously and manage their documents properly. This simple habit tells a lot about how they might handle bigger tasks.
First impressions happen quickly, and a neat file folder can help make the right one. When candidates present their documents in a well-kept resume portfolio folder, recruiters immediately see the effort behind it. A tidy folder shows confidence, readiness, and care.
Messy papers or unorganised files can create a negative impression. On the other hand, using a proper resume folder for interview strengthens the candidate’s overall professional image and makes them stand out.
Interviews require preparation, and a resume folder helps professionals stay ready. It keeps important documents safe, wrinkle-free, and easy to reach. Resumes, certificates, experience letters, and ID proofs stay organised inside a well-structured paper folder.
Carrying a resume folder also reduces stress. Instead of searching through bags or loose sheets, professionals can quickly open the folder and find what they need. This smooth experience helps them stay calm and present themselves with confidence.
Professionals with many years of experience often carry more than just one resume. They bring certificates, achievements, work samples, and project details. A good resume folder helps arrange these documents in a clean and clear format.
It also improves credibility. Senior candidates who use a well-organised set of resume folders or a premium folder file show that they respect their own professional journey. A clean folder supports their image and helps them stand out in competitive situations.
A file folder plays a simple but important role—it keeps everything in one place. From resumes and certificates to project sheets and ID cards, all documents stay secure and easy to find. This helps professionals in interviews, meetings, and client presentations.
A resume file folder also saves time. Instead of carrying multiple files or searching through loose papers, a single organised folder makes the process easier. It shows that the person values time and stays organised, which is something every employer appreciates.
Many experienced professionals prefer leather resume folders. A leather resume folder offers strength, a smart finish, and a premium look that suits every industry. It leaves a memorable impression during interviews, meetings, and presentations.
Leather folders also add confidence because they look and feel better than basic options. For people who want a long-lasting and stylish document organiser, leather is a practical choice.
When choosing a folder, many buyers check the document file price. Even though leather folders may cost more, they last longer and offer better value in the long run.
A resume folder is useful in many professional situations. Some examples include:
Job Interviews
Helps candidates present resumes and certificates clearly.
Promotion Meetings
Organised documents help employees show their achievements confidently.
Client Presentations
A professional resume folder keeps project files tidy and easy to access.
Corporate Events or Formal Submissions
Employees look more polished when handling official documents.
In all these moments, a clean folder or file folder helps professionals leave a strong and positive impression.
A resume folder is more than a document holder—it reflects professionalism, organisation, and preparation. Whether someone is a fresher or an experienced professional, carrying a proper resume folder improves confidence and makes them look more polished.
From organising important documents to creating a strong first impression, a resume folder supports career growth in many ways. For anyone who wants to stay ready, organised, and confident, investing in a quality folder is a smart decision.
*Q1. Do professionals really need a resume folder for interviews?

Over the last period I’ve been working on Luminara, a full-featured HTTP client built directly on top of native fetch.
The idea wasn’t to create “yet another wrapper,” but to build a complete request lifecycle around fetch — something that’s usually spread across multiple small libraries.
The project is open-source
👉 https://github.com/miller-28/luminara
Live sandbox and documentation
👉 https://luminara.website
Npm
👉 https://www.npmjs.com/package/luminara
In most real-world applications, a simple fetch() isn’t enough.
You eventually need:
Developers usually assemble this from several packages, custom utilities, or ad-hoc logic scattered across codebases.
Luminara tries to bring the entire lifecycle into one place — without adding dependencies, and without hiding fetch.
🙌 Looking for Feedback
I’d love to hear from other developers who have built or maintained HTTP layers:
Is the API intuitive?
Any design mistakes or surprising decisions?
Features you’d expect but don’t see?
Anything you'd simplify or reorganize?
Open to critique — architectural, naming, ergonomics, anything.

In today's world there are multiple levels of abstraction everywhere. Since why would you go extra mile to re-invent a wheel if the car already exists. Just like that there are multiple levels in java architecture as well. In that context, one of the in-build concept is Boxing.
Well its not a cardboard box where you store stuff. But it's a way to handle memory and objects by optimizing performance too. To understand Boxing, we first need to introduce ourselves 2 core techniques in java -
Primitive Data type refers to int, float, double etc. And Wrapper classes are Object Templates build around the data types to convert a primitive data type to corresponding Objects, like Integer, Float, Character etc.
Like,
Integer wraps int
Character wraps char
Now coming to the point of boxing - There are again 2 terminologies
In Autoboxing a primitive data type(e.g. int) is converted to its corresponding wrapper class(e.g. Integer)
List<Integer> li = new ArrayList<>();
for (int i = 1; i < 50; i += 2)
li.add(i);
In the example above, even though li is a Integer type ArrayList but the compiler autoboxes the primitive values to Integer to treat the elements as "int" objects. You can say this is one of the distinguishing factor between arrays and Lists.
And in Unboxing wrapper class is converted to its primitive type.
int sum = 0;
List<Integer> list = new ArrayList<>();
for (Integer i : list) {
// Unboxing of i automatically
if (i % 2 != 0)
sum += i;
// Unboxing of i is done automatically using intvalue implicitly
if (i.intValue() % 2 != 0)
sum += i.intValue();
}
for more info you can visit https://www.geeksforgeeks.org/java/autoboxing-unboxing-java/ as well as oracle docs.
Now where does Streams come into picture?
Java from version 8 onwards introduced Streams. Which are basically a unique way to handle stream/collection of objects. Previously how we used to handle collections is by using collections framework and arrays. But Streams provide a wide variety of usages as it supports functional programming and lambdas. It makes managing a pool of objects very swift.
As I said Streams are flow of objects not their primitives. You can have stream of employees, cars, and all kinds of objects. But what if you need to work with only int values. But here comes an extra hurdle of managing stream of objects. But java has a native solution to this problem - intStream. Let's say you need to search an item in a stream of employees and need to get int as return then use intStream.
This image is from one of my projects -
But why to use intStream not regular Streams-
Well, I am not very good at explaining but dear readers you can always google it, oops😅 I mean GPT it.😁

I recently installed Fedora Linux alongside Windows on my laptop, and here are the steps I followed. I’m sharing this to help anyone facing similar issues, especially with partitioning and EFI placement.
I created an empty partition for the Fedora environment.
However, I ran into a problem: my EFI System Partition was located between C: and the unallocated space, so Windows Disk Management wouldn’t let me extend or merge the partitions properly.
Since I also had a D: drive, the layout became messy.
To fix this, I used IM-Magic Partition Resizer to move the EFI System Partition to the far right, which allowed me to merge the unallocated space into the partition I wanted.
If your laptop only has a single C: drive, you probably won't encounter this.
I downloaded Fedora Media Writer from the official website.
Fedora Workstation
Plug in your USB stick (4GB or more).
Install and open Fedora Media Writer.
Select Fedora Workstation and make sure the target directory is your USB drive (it usually detects it automatically).
Write the image to the USB.
Restart your laptop, open the boot menu, and choose to boot from the USB drive.
Once Fedora Live Mode loads, check basic hardware support first (WiFi, Bluetooth, audio, etc.).
When you’re ready, begin the installation.
Choose how much space you want to allocate.
After installation, reboot and select Windows Boot Manager.
Check if Windows works properly and verify that your C: drive size has decreased based on the Fedora partition you created.
Safely remove your USB stick and restart again.
This time, choose Fedora from the boot menu.
Your dual-boot setup is now complete!

Create a simple EC2 instance using:
Using your backend resources:
We keep it clean for this task:
terraform-ec2-basic/
├── backend.tf
├── main.tf
├── variables.tf
├── outputs.tf
├── terraform.tfvars
🧩 backend.tf
terraform {
backend "s3" {
bucket = "tf-backend-lab-123"
key = "ec2/basic/terraform.tfstate"
region = "us-east-1"
encrypt = true
dynamodb_table = "tf-state-lock"
}
}
📌 variables.tf
We define input variables:
variable "instance_type" {
description = "EC2 instance type"
type = string
default = "t3.micro"
}
variable "ami_id" {
description = "AMI ID for EC2 instance"
type = string
}
variable "env" {
description = "Environment name"
type = string
default = "dev"
}
variable "owner" {
description = "Owner/Team name"
type = string
}
🧠 locals
Locals are used to build consistent resource names.
Add this inside main.tf or create locals.tf
locals {
name_prefix = "${var.env}-${var.owner}"
common_tags = {
Environment = var.env
Owner = var.owner
ManagedBy = "Terraform"
}
}
Interview Tip:
Locals help avoid repeating variables and maintain consistent naming conventions.
📌 main.tf
provider "aws" {
region = "us-east-1"
}
resource "aws_instance" "server" {
ami = var.ami_id
instance_type = var.instance_type
tags = merge(
local.common_tags,
{
Name = "${local.name_prefix}-ec2"
}
)
}
📤 outputs.tf
output "instance_id" {
value = aws_instance.server.id
description = "EC2 Instance ID"
}
output "public_ip" {
value = aws_instance.server.public_ip
description = "Public IP address of the EC2 instance"
}
output "tags_used" {
value = local.common_tags
}
📌 terraform.tfvars
Provide your values:
ami_id = "ami-0c02fb55956c7d316" # Amazon Linux 2 in us-east-1
owner = "lachu"
env = "dev"
instance_type = "t3.micro"
terraform init
terraform validate
terraform plan
terraform apply -auto-approve
If you can check with dynamoDB table
✔ Why use variables?
✔ Why use locals?
✔ Why use outputs?
✔ Why S3 + DynamoDB?
✔ Typical interview question:
How does Terraform handle state locking?
Answer:
When using S3 backend with DynamoDB, Terraform creates a lock entry in DynamoDB during operations such as plan or apply. This prevents concurrent modifications of the state, ensuring consistency.
