Why It’s More Than Just Technical Knowledge

highlighting your soft skills in an interview process

When interviewing for roles like Rack Install Technicians or Data Centre Technicians, it’s not just about your hands-on skills. You also need to show that you understand the environment: strict processes, uptime pressure, and precision.

You might be great with fibre and cable runs—but if you can’t follow procedures or check your work properly, you’ll struggle.

What Technical Skills Do You Really Need?

It depends on the role—but usually includes:

Installing racks, rails, and equipment
Running fibre and copper cabling neatly
Following diagrams or rack plans (RFD/RFP)
Asset tagging and updating systems
Working in live environments with caution

Tip: When asked about experience, be specific. Mention tools you’ve used (e.g. torque screwdrivers, fibre testers), or systems you've worked with (e.g. DCIM, ticketing systems like ServiceNow).

What soft skills are hiring managers in Data Centre looking for?

Reliability: The One Thing Every Site Needs

In fast-paced data centre projects, showing up on time, following instructions, and doing clean, consistent work is crucial. Clients rely on teams that don’t cut corners.

What reliability looks like in interviews:

Showing up 5–10 minutes early
Being honest about availability and shift work
Giving examples of meeting deadlines or staying late to finish a task

Attitude & Adaptability: Why They Still Ask About Soft Skills

Even if the job is technical, many interviewers still ask things like:

“What would you do if you made a mistake on site?”
“How do you handle pressure or changes to plans?”

They want to see if you’ll stay calm, take responsibility, and follow escalation steps.

Tip: Mention a time you had to adapt—like learning a new system, working under a tight deadline, or fixing an install issue.

Team Fit: Often Overlooked, But Important

You’re often working in small teams on critical jobs. Being easy to work with matters.

You don’t need to be overly chatty—but listening, helping others, and asking questions the right way shows you’re a team player.

Common Mistakes Candidates Make

Giving generic answers – Instead of saying “I have rack install experience,” talk about the type of installs, environments (cold/warm aisles), or tools used.
Not knowing the job description – One candidate showed up thinking it was IT support—it was rack deployment.
Not asking questions – Asking about shift patterns, team size, or job expectations shows interest.
