Certifications That Get You Hired

Certifications are a shortcut for proving you have a baseline of knowledge to someone who has never met you. For a career-starter with no professional experience, that signal can be the difference between getting an interview and being filtered out by an automated screen. But a cert is a door-opener, not a career — it works best when it sits on top of real hands-on skill.

Why certifications help career-starters

When you have no job history to point to, a hiring manager has to take a risk on you. A recognised certification reduces that risk in a few concrete ways.

  • They pass automated filters. Many job posts list a cert as "required" or "preferred", and applicant-tracking systems screen for those keywords.
  • They prove you can finish something. Studying for and passing a structured exam shows discipline and follow-through.
  • They give you a vocabulary. Certs force you to learn the standard terms, so you can talk to senior engineers without getting lost.
  • They structure your learning. An exam objectives list is a free, vendor- vetted curriculum. Even if you never sit the exam, the syllabus tells you what matters.

What certs do not do

A certificate does not make you a sysadmin any more than a driving-theory pass makes you a driver. Hiring managers know this. The candidate who passed Linux+ and runs a home lab with broken-and-fixed servers beats the candidate who only memorised exam dumps, every time.

The limits of certifications

The trap The reality
"I'll get five certs, then apply" Two relevant certs plus a portfolio beats five unrelated ones.
"Brain-dump sites will get me through" You will pass the exam and fail the interview. Skills show.
"A cert guarantees a salary bump" It helps you get hired; pay comes from what you can actually do.
"Higher-level cert first" You will drown. Build the foundation before the expert exam.

Treat certs as complements to practice, never replacements. The ideal loop: learn a topic, build it in your lab, then certify it to make it official.

The main certifications by path

Pick a path first, then a cert. The big paths are: general IT foundations, Linux, Microsoft/Windows, cloud, and networking.

Certification Vendor Level Who it's for
CompTIA A+ CompTIA Entry Total beginners; help desk and desktop support
CompTIA Network+ CompTIA Entry Anyone touching networks; vendor-neutral basics
CompTIA Linux+ CompTIA Entry–Junior Linux beginners wanting a vendor-neutral cert
CompTIA Security+ CompTIA Entry–Junior Anyone; baseline security, often a hiring requirement
RHCSA Red Hat Junior–Mid Aspiring Linux admins; hands-on, lab-based exam
RHCE Red Hat Mid RHCSA holders; automation with Ansible
LFCS Linux Foundation Junior Linux admins; distro-flexible, performance-based
LFCE Linux Foundation Mid LFCS holders; engineering-level Linux
AZ-900 Microsoft Entry Cloud/Azure newcomers; concepts, no deep tech
AZ-104 Microsoft Mid Azure Administrators; the core Azure ops cert
Windows Server (role-based) Microsoft Junior–Mid Windows-shop admins; AD, GPO, server roles
AWS Cloud Practitioner AWS Entry Cloud newcomers; AWS concepts and billing
AWS Solutions Architect – Associate AWS Mid Designing AWS systems; very widely recognised
AWS SysOps Administrator – Associate AWS Mid AWS operations and day-to-day administration
Google Associate Cloud Engineer Google Entry–Mid Deploying and operating on Google Cloud
Cisco CCNA Cisco Junior–Mid Networking careers; the gold-standard entry network cert

Performance-based vs multiple-choice

Exams like RHCSA and LFCS are done on a real terminal — you fix actual systems against a clock. They are harder to fake and carry more weight with technical interviewers than multiple-choice exams. If you can pass one, it tells an employer you can do the job, not just describe it.

Which cert should you start with?

Your first cert depends on the direction you have chosen. If you are still deciding, read What is a Sysadmin? and the career roadmap first.

Start with CompTIA A+ or Network+. They are broad, vendor-neutral, and respected for help-desk and junior support roles — a safe on-ramp that keeps every later path open. Add Security+ if security interests you; it is a common baseline requirement.

Aim for RHCSA (or LFCS if you prefer a distro-neutral, slightly cheaper route). This is the single highest-value cert for a Linux career- starter because it is hands-on. Follow it with RHCE once you are comfortable. Pair your study with the Linux track.

Start with AZ-900 for the concepts, then AZ-104 for real Azure administration. If the role is on-prem Windows, target the role-based Windows Server certification and learn Active Directory.

Begin with AWS Cloud Practitioner (or AZ-900 / Google ACE) to learn the vocabulary and billing model, then move to an associate-level cert such as AWS Solutions Architect – Associate or SysOps Administrator – Associate. Cloud certs assume you already know basic Linux and networking, so build that first.

Go straight for CCNA. It is demanding but it is the recognised entry networking cert, and it opens NOC and network-technician roles. Consider Network+ first if subnetting and the OSI model are completely new to you.

A realistic sequence

For most people starting from zero and aiming at Linux/hosting:

  1. Network+ or A+ — get comfortable, learn the language, pass something.
  2. Build a home lab and break things on purpose.
  3. RHCSA or LFCS — the cert that actually proves Linux skill.
  4. A cloud associate cert (AWS/Azure/GCP) once you are working or job-hunting.
  5. RHCE / Security+ / specialisations as your role demands them.

Do not buy the next exam voucher until you can comfortably do the things the last one covered, without notes, in your lab.

Watch the renewal clock

Most certs expire (often after 2–3 years). Vendor exam costs vary by country and change over time, so check current pricing on the official site rather than trusting a forum post. Factor renewal effort into how many certs you chase — an expired cert on a resume can look worse than none.
