When I started looking for a remote IT internship, I wanted something more than just watching tutorials and doing test tasks in a sandbox. I wanted to work on something real — a live website. That is exactly what I got during my three months at Katrium.
If you are a computer science student looking for a remote internship that gives you hands-on technical experience, this article is for you.
Why I Chose Katrium for My Remote IT Internship
I found the IT-intern position at Katrium through a Google search and applied directly mostly because of two things: the role was fully remote, and the tasks were genuinely technical. No coffee runs, no Excel copy-paste. The internship description mentioned website management, SEO analysis, and tool research — things that actually aligned with what I was studying.
Moreover, Katrium is an international outsourcing company based in Tallinn, Estonia, working with clients across Europe and North America. The team is fully remote and multilingual, which meant working in an environment closer to a real international tech company than a typical local internship.
What I Actually Did At Katrium — The Technical Side
This is the part I wish someone had described before I started. Here is a breakdown of what my day-to-day work looked like at Katrium.
Building and Publishing Web Pages
The biggest part of my internship was building landing pages and service subpages for the Katrium website from scratch. I worked in WordPress, going from a Figma mockup to a fully published page. Over three months, I built pages across all major Katrium’s service categories: Market Research, Multilingual HR & Recruitment, Contact Center and Business Support.
This was not just dragging and dropping pre-made blocks. I wrote and edited HTML within individual page sections and made custom CSS edits directly in the global site stylesheet. I debugged layout and alignment issues, handled backend form integrations, tested plugin compatibility, and made sure everything worked correctly after publishing.
I also managed multilingual versions of the website in English, Estonian, and Finnish — keeping content, URL slugs, and internal links consistent across all three language versions simultaneously.
SEO and Website Performance
SEO was a continuous thread throughout the internship. I conducted keyword research, analysed popular website structures, audited content formatting (H1-H4 hierarchy, internal linking, keyword placement), and checked new pages with SEO tools before and after publishing.
On the performance side, I analysed page speed, investigated plugin conflicts and researched solutions for redirect problems found in the sitemap.
UX Research: A Homepage Heatmap Study
One of the more unexpected parts of the internship was running a UX research study. I designed and conducted a heatmap-based usability test for the Katrium homepage with 12 participants over three days, then synthesised the findings into a summary report that informed design decisions. It was a small but complete research cycle, planning, running sessions, analysing patterns, and drawing conclusions.
Plugin and Tool Evaluation
Throughout the internship I regularly researched and compared technical tools before implementing them — evaluating Elementor versus Gutenberg, testing mega menu plugins (ElementsKit, Max Mega Menu), comparing Smart Slider options, and auditing form plugins. Making informed decisions about which tool to use and being able to justify that choice is a skill I did not expect to develop during an internship, but it turned out to be one of the most practically useful things I worked on.
What I Learned in 3 Months
Honestly, more than I expected. Here are the things that stayed with me:
- WordPress and Elementor are tools, but the real skill is knowing when to use custom HTML and CSS instead of relying on the builder. I learned that lesson by debugging padding and alignment issues for longer than I want to admit.
- SEO is not a checklist — it requires understanding why search engines rank content the way they do, which means reading, testing, and iteration.
- Remote work requires stronger self-organisation than on-site work. With weekly check-ins rather than daily oversight, I had to manage parallel projects, communicate blockers early, and make independent decisions.
- Working internationally means communication clarity matters more than in a local team. Things that feel obvious in your native language are not always obvious across cultures and time zones.
Should You Apply for a Remote IT Internship at Katrium?
If you are a computer science student who wants to work on something real rather than practice exercises, yes. The internship at Katrium is not structured like a university course — you will not be guided step by step through every task. You will be given a goal and expected to research, test, and deliver.
That is both the challenge and the value. By the end of three months, I had a portfolio of real, published web pages on a live website, production-level SEO experience, and a much clearer sense of where I want to go in my career.
Katrium offers international internship positions for students from various backgrounds. You can check current openings on the Katrium International Internships page.
Final Thoughts
My remote IT internship at Katrium was a practical, fast-paced experience that gave me skills I could not have picked up in a classroom. Building real pages for a real company under real deadlines is different from any academic project — and that difference matters when you are applying for your first job.
