Introduction

Linkedin intro CN

Are you seeking a challenging job where you can utilize DevOps to the fullest extent possible and even go a little further? A position as a site reliability engineer would be ideal.

Here, we'll provide you with a detailed road map for obtaining your ideal position.

The Site Reliability Engineer at LinkedIn, the necessary skill sets, road maps, and significant connections that you can also refer to are all covered in this piece.

LinkedIn Preparation Guide

LinkedIn Preparation Guide

Before the DevOps movement, in 2003, the first team of software engineers at Google was entrusted with increasing the dependability, efficiency, and scalability of Google's already sizable websites. Site reliability engineering (SRE) was born as a result. They created procedures so effectively meeting Google's requirements that other major digital firms, like Amazon, Netflix, and LinkedIn, adopted them and introduced new techniques.

SRE gradually developed into a full-fledged IT domain to create automated solutions for operational aspects, including on-call monitoring, performance, capacity planning, and catastrophe response. It complements other fundamental DevOps techniques like infrastructure automation and continuous delivery.

Consider working for a business that creates items millions of people use every day worldwide. We'll talk about one such company in this piece, Linkedin. We'll look at the business and the LinkedIn interview process for professionals and software engineers. We'll also look at advice on how to get ready for and get hired at LinkedIn as a software engineer. Later, we'll review some of the most typical LinkedIn interview questions.

LinkedIn

Let's first learn a little bit about LinkedIn before moving on. LinkedIn is the name of the largest professional networking platform in the world. Its main office is in Sunnyvale, California, established in 2003. Software engineers, By enabling people to share their experience, knowledge, and practical skills with those who might need them, professionals can use Linkedin to employ someone, find a job or internship, connect with others in the field, and develop existing professional ties. One can organize events, publish updates, join organizations, or publish blogs that millions of people can read on Linkedin.

Ways to Join LinkedIn

Ways to Join LinkedIn

Automating operational duties is a critical component of the specialized IT position known as SRE. Both developers aiming to manage massive infrastructures and systems engineers looking to advance their programming abilities may find the position to be a good fit. Candidates with expertise in software development, automation, and a wide range of associated tools will have an edge during the interview.

Any SRE interview will subject candidates to various inquiries or practical tests designed to gauge their understanding of whole site reliability skill sets. While the specific requirements of the employing firm may affect these questions or examinations, The five essential interview topics that an SRE candidate might anticipate are software development, monitoringdebugging, networking, infrastructureoperations, and business-side concerns.

Software Development

Software Development

The first interview questions in this field typically probe a candidate's fundamental understanding of the programming languages used by the company, such as Perl or Java, along with data structures like queues, stacks, heaps, and algorithms. This part of the interview may require the candidate to examine the code to find flaws, inefficiencies, and locations where the code might malfunction or result in unpleasant outcomes, which are crucial concerns for software reliability. Other considerations about software development might include critical applications and interfaces, including databases, with a focus on interoperability and configuration difficulties that can impact the stability and performance of an application.

Monitoring and Troubleshooting

Monitoring and Troubleshooting

SRE interview questions in this category frequently test candidates' understanding of monitoring principles and practical knowledge of specific tools or approaches. For instance, the interviewer can ask how to parse a log file to produce a CSV of particular events or processes or how to measure database query durations, a crucial aspect of performance monitoring.

Networking

Networking

Networks are essential to computing and service delivery, but SREs are not network engineers. Candidates for SRE positions should be proficient in networking and be able to respond to a variety of real-world network questions.

These questions range from being very simple to being quite challenging. The interviewer may ask a candidate to define or describe fundamental networking terms like DNSDynamic Host Configuration Protocol, or TCP/IP as a simple question. However, networking inquiries can quickly grow more specific and in-depth. For instance, the interviewer might inquire about the specifics of a TCP connection configuration or how to compute the amount of usable IP addresses on a /23 network.

Infrastructure and Operations

Infrastructure and Operations

Various infrastructure and operations-related questions will often be presented to an SRE candidate; some fundamental ones will usually concern OSes and security. An interviewer might inquire, for instance, what occurs when the ps command is typed into a UNIX prompt. Candidates may be asked to describe how to secure a container image or the distinction between RAID 0 and RAID 5—as well as when to employ either over the other. The difference between a service-level agreement (SLA) and service-level indicator, as well as the variations between virtualization, containers, and Kubernetes, are other fundamental issues.

Business-side Issues

SREs are primarily concerned with technological operations, but due to their high level and broad scope, they can also be involved in business initiatives and decision-making. SREs who are successful need to have a firm grasp of crucial business-side challenges.

The value of error budgets may be a topic of discussion for SRE candidates. An error budget is the longest a system can be down without going against an SLA or other performance obligation.

How to become a Site Reliability Engineer 

SRE creates extremely dependable systems by fusing software engineering and IT engineering techniques. The reliability of the entire stack—from the front-end, customer-facing applications to the back-end database and hardware infrastructure—is the responsibility of site reliability engineers.

An SRE is in charge of each of these areas:

  • General systems uptimes
  • Systems performance
  • Latency
  • Incident and outage management
  • Systems and application monitoring
  • Change management
  • Capacity planning

Knowing How to Code

Due to the SRE function's nature, development and coding knowledge might be pretty helpful.

What language makes the most sense to learn right now? Knowing PythonGo, or Java can be beneficial in the long term because automating procedures and working with systems are part of an SRE's daily responsibilities.

Understanding Operating Systems

Understanding Operating Systems

Large-scale server operations can be a little stressful. A firm understanding of the operating system is utilized by your business, typically Linux or Windows. You'll frequently work with these operating systems as an SRE.

CI/CD

CI/CD

The SRE and DevOps roles differ in that they both implement DevOps methods, yet both parts share several characteristics. One of them is continuous integration and deployment. You must be able to create a CI/CD pipeline from scratch for any application to be a top-notch SRE.

Using Version Control Tools

Using Version Control Tools

As a software engineer, you'll use Git or another version control tool when dealing with code. Therefore, becoming familiar with version control tools makes sense. The best way to do this is to become familiar with GitHub and Git.

Using Monitoring Tools

Best Application Monitoring Tools - DNSstuff

When you work as an SRE, monitoring tools make your life simpler. They give you a quick overview of your system's operation and any problems it may have. The main objective of SRE is to implement these technologies and gain insights from them to minimize downtime for the system.

Cloud Native Applications Can Make Your Life Easier

What are Cloud Native applications?
