How interviews often run in Germany

These published notes describe general preparation. They do not confirm one employer's process. Check your invitation, and ask the recruiter if anything is unclear.

  • The interview is held in the language of the job advert, but expat career guides commonly report that an interviewer may switch to German part-way through, even for a role advertised in English. Decide in advance how you will handle that: answer in German at your level, or ask politely to continue in English. (Source: expatrio.com, iamexpat.de)
  • Contracts and most workplace paperwork are usually in German. Being open about your current level is generally read better than avoiding the question. (Source: findenglish.de)

Sentence starters for a software engineer interview

Common mistakes for non-native speakers

In Germany, interviewers often like a real example more than big words. Say what you did and the result, then stop. The evidence you give is the same; only the way you say it changes.

  • Instead of starting with technical detail: say: "The problem was… The result was… Here is how I did it". An interviewer may follow the detail more easily once they know where it ends.
  • Instead of "We built it": say: "I wrote the API, and my colleague built the front end". Say "I" for your part, so your own work is clear.
  • Instead of thinking silently in a coding round: say: "First I will check the input, then I will try a simple version". Interviewers often want to hear how you think, not only the final code.
  • Instead of "I don't know": say: "I have not used that yet. The closest thing I have used is… and I would start by…". It shows how you learn, which is often what the question is about.
