Why L3Harris? How to Answer the Motivation Question

A practical guide to answering 'Why do you want to work at L3Harris?' โ€” how to research the company, structure a genuine answer, and avoid generic responses that fall flat.

Why interviewers ask 'Why L3Harris?'

Defence and aerospace companies like L3Harris ask this question for a specific reason: they need people who will stay engaged through long programme cycles, security clearance processes, and work that's often mission-critical rather than fast-moving or trend-driven. A vague answer signals you haven't thought about the fit; a specific one signals you have.

Interviewers are also listening for whether you understand what L3Harris actually does. It's a large defence and aerospace technology company formed from the 2019 merger of L3 Technologies and Harris Corporation, working across areas commonly associated with the business such as space and airborne systems, communications, sensors, and electronic systems for defence and government customers. You don't need insider knowledge โ€” you need to show you've done basic homework and can connect it to your own motivation and skills.

What a strong answer actually contains

A convincing 'Why L3Harris?' answer usually has three ingredients: a genuine personal or professional reason for wanting this kind of work, a specific detail about the company or role (not just 'you're a leader in the industry'), and a link back to what you'd bring to the team. Missing any one of these makes the answer sound either generic or self-serving.

  • Personal motivation โ€” why this type of work (mission-driven, technical, long-term programmes) genuinely appeals to you
  • Specific company or role detail โ€” something from the job description, a technology area, or a programme type, not a copy-pasted mission statement
  • Your contribution โ€” a skill or experience that connects your background to the role you're applying for
  • Delivered in under 90 seconds, conversationally, without sounding rehearsed

Do this, not that

Here's how the same underlying motivation can sound either forgettable or memorable, depending on how it's phrased.

  • Don't say: 'I've always wanted to work for a big, respected company like L3Harris.' โ€” Do say: 'I want to work on systems that have a real operational impact, and this role's focus on [specific technology area from the job ad] is exactly the kind of engineering problem I want to spend my career on.'
  • Don't say: 'You're a leader in defence technology.' โ€” Do say: 'I read about the type of work this team does on [programme area/technology], and it's a step up in complexity from what I've worked on, which is exactly the challenge I'm looking for.'
  • Don't say: 'I need a stable job.' โ€” Do say: 'I want to build my career somewhere I can go deep on one technical area over several years rather than jumping between short projects, and that long-cycle, mission-focused environment is what draws me here.'
  • Don't recite the company's public mission statement word-for-word โ€” paraphrase it and add your own reasoning for why it resonates.

Reading about it isn't the same as doing it on camera.

Structure your answer like a mini-STAR

'Why this company?' isn't a classic behavioural question, but borrowing STAR logic (Situation, Task, Action, Result) helps you avoid rambling. Instead of Situation-Task-Action-Result, use: Context (what draws you to this field), Specific (what you noticed about L3Harris or the role), Skills (what you bring), and Summary (a confident closing line).

Here's a worked example combining those elements:

  • Context: 'I've spent the last four years in systems engineering on communications hardware, and I've realised the work I find most satisfying is when the end product genuinely matters operationally โ€” not just commercially.'
  • Specific: 'When I looked at this role, the focus on [specific system/technology area mentioned in the job description] stood out because it's a step beyond what I've worked on, and it sits at the intersection of hardware reliability and mission-critical performance, which is where I want to grow.'
  • Skills: 'I've led integration testing on two hardware programmes end-to-end, including working directly with customer requirements documents, so I understand how demanding that kind of specification-driven work is.'
  • Summary: 'That combination โ€” mission-relevant work, long-term technical depth, and a team solving harder problems than I've tackled before โ€” is why this role is a strong fit for where I want my career to go.'

Researching L3Harris properly before your interview

You don't need classified insight โ€” you need public, verifiable detail. Spend 30โ€“45 minutes before your interview doing focused research rather than skimming the homepage.

Use what you find to build one or two specific reference points you can drop into your answer naturally, rather than listing facts.

  • Read the actual job description twice and note the specific technology, product, or programme type it mentions
  • Check L3Harris's investor relations or newsroom pages for recent, publicly announced programme wins or technology areas relevant to the role
  • Look at the specific business segment you'd be joining (the role advert or LinkedIn will usually indicate this) rather than talking about the company as one undifferentiated whole
  • If you know current or former employees, ask what a typical week actually looks like โ€” this often surfaces better material than public sources

Common mistakes that weaken this answer

Most weak answers to 'Why L3Harris?' fail for one of a few predictable reasons โ€” and they're easy to fix once you spot them.

  • Talking only about the company, never connecting it back to your own skills or goals
  • Being so general the answer would work for any large defence or aerospace employer
  • Overclaiming knowledge of L3Harris's internal processes or classified programme details you couldn't legitimately know
  • Focusing entirely on salary, stability, or benefits rather than the actual work
  • Speaking for over two minutes โ€” this question should be tight and confident, not a monologue

Practising your answer under real interview conditions

Knowing what to say and being able to say it fluently under time pressure are different skills โ€” this question often comes up early in a screening call or a timed one-way video interview, and rambling in the first 90 seconds sets a bad tone for the rest. It's worth practising your answer out loud, on camera, with a timer running, so it comes out naturally rather than sounding memorised.

ScreenReady lets you rehearse this exact scenario โ€” a timed, one-way video interview format similar to what many large employers use โ€” and gives you AI feedback on pacing, clarity, and structure, so you can tighten your 'Why L3Harris?' answer before the real thing.

Frequently asked questions

How long should my answer to 'Why L3Harris?' be?

Aim for 60โ€“90 seconds. Long enough to include a genuine reason, a specific detail, and a link to your skills, but short enough to stay tight and confident rather than rambling.

What if I don't have a defence or aerospace background?

Focus on transferable motivation โ€” precision, reliability, mission impact, or long-term technical depth โ€” and be honest that you're drawn to the sector for those reasons rather than pretending prior experience you don't have.

Can I mention pay or job security as a reason?

It's fine as a minor point but shouldn't be your main answer. Interviewers want to hear that you're motivated by the work itself, not just the practical benefits of the job.

Should I mention the L3Harris merger history?

You can reference it briefly to show you understand the company's scale and background, but don't lead with it โ€” it's context, not your motivation, so keep it to a single sentence at most.

How specific do I need to get about the technology or programme area?

As specific as the job description allows. Referencing the actual technology area, systems type, or business segment named in the advert shows you've read it carefully, which matters more than reciting company-wide facts.
