Start with one question and one real example
Choose a question you expect to face and an experience you can discuss honestly. Before speaking, note the setting, the decision you made and what happened. Keep those notes to a few words so you still have to explain the experience in your own language.
Record an answer or speak to a practice partner. A first attempt shows where you search for words, leave out context or repeat yourself. Listen once without rewriting the whole answer.
Review the content before polishing delivery
Write down the point you think the listener should remember. Then check whether the recording actually explains it. If the question asks about your contribution, a long project description may leave the main question unanswered.
- Where did I answer the question directly?
- Which decision or action was mine?
- What changed, and what supports that conclusion?
- Which sentence repeats information the listener already has?
Try a follow-up without reading a script
Ask why you chose that approach or what you would change next time. Speak again from the facts, rather than memorising your previous wording. When a fact is missing, return to your records or acknowledge the limit.
Practising in English can help you find familiar words for your work. An accent does not establish whether the reasoning is sound. Focus on whether a listener can follow your explanation, then adjust pace and phrasing where they obscure it.
Keep a short practice record
After each attempt, save the question, the part that was unclear and one change for the next attempt. Try a related question later without the notes. An answer becoming easier on the original question does not yet show that you can adapt it to a new one.
