How to prepare for a technical job interview
A technical interview is rarely just about technology. Here's how to prepare for the questions that really matter.
A technical job interview is rarely decided on technical knowledge alone. The employer mainly wants to know how you think, how you collaborate and whether you fit the way the team works. Good preparation makes that visible.
Before the interview
Pick three projects from your career that you know in detail: what was the problem, what did you do exactly, what was the result? Almost every behavioural question can be answered with one of those three stories. Also reread the vacancy and note where your experience matches exactly.
Look up who you'll be talking to. A conversation with a production manager runs differently from one with an HR manager. With the first you can dive deeper into the technology; with the second, motivation and collaboration matter most.
During the interview
Answer concretely. 'I have a lot of PLC experience' convinces less than 'I migrated the controls of two packaging lines from S7-300 to S7-1500'. Details make you credible, even when you can't answer every question perfectly.
Don't know something? Say so honestly and explain how you'd find out. In technical environments, a reliable colleague who knows their limits outweighs someone who improvises an answer to everything.
Questions you ask
Prepare at least three questions of your own. Ask about the machine park or technology, how the team is put together, and what success in this role looks like after a year. Your questions show your level just as much as your answers. And remember: you're evaluating the employer just as much as the other way round.
Frequently asked questions
How long does a technical job interview usually take?
Count on 45 minutes to an hour for a first interview. If a technical round or a shop-floor tour follows, it can run to two hours. Ask in advance what's on the agenda.
Should I share my salary expectation in the first interview?
You don't have to be the first to name a figure, but don't fear the question. A range works better than a single number. If you apply via AltusConnect, we know the vacancy's range and discuss it with you beforehand.
What if I can't answer a technical question?
Say honestly that you don't know and explain how you'd approach it: documentation, a colleague, a test. Employers aren't looking for a walking encyclopedia but for someone who handles the limits of their knowledge reliably.
