Prepare stories, not answers
Interview questions vary in wording, but the underlying stories they are trying to surface, a challenge you solved, a disagreement you navigated, a project you led, tend to repeat. Prepare four or five career stories in detail, in your target language, rather than trying to guess and memorise exact answers to specific questions. You can adapt a prepared story to several different phrasings of a question.
Practise the structure out loud
A common structure for interview stories is situation, task, action, result. Practising this structure out loud, not just thinking through it silently, reveals where your language breaks down: verb tenses for past projects, vocabulary for describing outcomes, or transitions between the parts of the story. Speaking the story several times, changing small details each time, builds flexibility instead of a rigid memorised script.
Prepare for the unscripted moments
Small talk at the start, clarifying questions in the middle, and your own questions at the end are often less rehearsed than the core interview questions, but they still shape the impression you leave. Prepare two or three natural opening lines, a few clarifying phrases like 'Could you tell me more about what success looks like in this role?', and two thoughtful questions to ask the interviewer.
Rehearse recovery language
Even well-prepared candidates sometimes lose a word or need a moment mid-answer. Rehearsing phrases like 'Let me rephrase that' or 'Give me a second to find the right word' in advance means you have them ready under pressure, instead of freezing. Interviewers generally respond well to calm recovery and poorly to a long silent pause.
Do a full run-through under time pressure
In the final days before an interview, do at least one full run-through with a timer and, ideally, another person asking questions in a different order than you expect. This surfaces gaps that quiet, untimed practice tends to hide, and it builds familiarity with performing under mild pressure, which is closer to the real interview experience.
