The difference between technical/functional interviews and culture-fit interviews and how to prepare for both

A technical interview, often called a functional interview outside IT and engineering, tests whether you can do the job. A culture-fit interview tests how you'll do it, and whether you'll work well with the people around you. Most senior hiring processes include both, sometimes in the same conversation, so it helps to know which question you're really being asked and prepare for each on its own terms.

What does a technical or functional interview test?

"Technical interview" is the usual term in engineering and IT. In marketing, finance, product or operations, the same round is more often called a functional interview. In German-speaking companies, both go by the name "Fachgespräch". The interview is usually led by the hiring manager or future peers and aims to go deep, testing you on your craft and methods.

What interviewers want to see:

• Real depth, not buzzwords. Can you explain how you'd approach a problem in your field, step by step?

• Your reasoning. Why did you choose one method, tool or approach over another, and what are the trade-offs? What are your past experiences with other methods?

• Honesty about limits. Saying "I haven't done that, but here's how I'd find out" lands far better than bluffing.

Depending on your field, this round might include a live exercise, a portfolio walkthrough or a take-home case study.

What does a culture-fit interview test?

A culture-fit interview is about how you work: how you make decisions, handle disagreement, give and take feedback, and what kind of environment brings out your best. It's often run by the hiring manager, HR or the wider team.

Good interviewers aren't looking for someone who's just like them. Many companies now talk about "culture-add": what new perspective or strength you'd bring. Either way, they're checking two things: that your values and working style fit the team, and that you'd be happy there too.

How to prepare for both rounds

For the technical or functional interview

• Pick the 3–5 hard skills the job description stresses most and refresh the fundamentals behind each

• Prepare two or three examples where you made a trade-off, and be ready to explain why

• Have one story about something that went wrong and what you changed afterwards

• Practise explaining your work out loud, as if to a smart colleague from another team

For the culture-fit interview

• Read how the company describes itself (careers page, values, founder interviews) and note what feels true for you

• Prepare stories about disagreement, feedback and a decision you made with incomplete information

• Think about the environment where you do your best work, and be honest about it

• Write down a few questions about how the team actually works: how decisions get made, how conflict is handled, what a good first year looks like

What changes at a senior level?

At senior level, the line between the two rounds blurs. Technical interviews start asking how you'd set direction for a team, not just how you'd solve the problem yourself. Culture-fit conversations focus on leadership style: how you build trust, handle underperformance and work with stakeholders you don't manage.

It's also a two-way test. You're deciding whether this is a culture you want to lead in, so use your questions to find out.

What's specific to Germany, Austria and Switzerland?

• Expect substance. Interviewers often value precise, well-reasoned answers over a polished pitch. Concrete examples with clear results go a long way.

• Culture fit is often woven into other rounds. Rather than a separate "culture interview", it may come up in the hiring manager conversation or a team meeting.

FAQ

Is a functional interview the same as a technical interview? Largely, yes. Both test the hard skills of your role. "Technical" is common in engineering and IT, while "functional" is used for most other business roles.

Can I fail one round and still get the job? It happens, but it's rare. A strong technical round can sometimes outweigh a slightly weaker culture-fit conversation, but serious concerns in either usually end the process.

How do I answer culture fit interview questions without sounding rehearsed? Use real stories and include what you'd do differently next time. Honest reflection sounds far more genuine than a perfect answer.

Key takeaways

• Technical interviews test what you can do, culture-fit interviews test how you do it.

• Prepare trade-offs and honest examples for the first, real stories about how you work for the second.

• At senior level, both rounds focus on leadership and direction.

• Use culture-fit conversations to check whether the company fits you too.
