I picked three interview questions people often struggle to answer off the cuff. Unless you have the gift of the gab, a bit of preparation helps. Even if you do, it helps to know what you are trying to say.
The questions are: “Tell me about yourself”, “What are your weaknesses?” and “Why are you leaving your job?” You don’t need a polished speech for each one. You need an honest answer that helps the interviewer understand your experience, judgement and reasons for being there.
For engineers and technical sales candidates, that means connecting your answers to work you have actually done. No invented achievements, and no borrowed answer that sounds impressive until someone asks a follow-up question.
1. “Tell me about yourself”
Start with the professional version of you. Your specialism, the work you do and the experience that matters to this vacancy. You don’t normally need to begin with where you grew up and work forwards from there.
Explain what you have been responsible for, then choose one relevant piece of work that shows your contribution. What was the task? What did you do? What was the outcome? Keep the distinction between your contribution and the team’s work clear.
For engineering work, think about the products, processes, equipment or projects that connect with the vacancy. For technical sales, think about the customers, products, sales activity and commercial responsibility you actually understand. The aim is to help the interviewer place your experience, not to list every task you have ever done.
Finish by explaining why this opportunity interests you. Link that to the work, responsibility or development available, using what you have learned about the role. “I’m looking for a new challenge” doesn’t tell them much on its own.
Prepare notes under three prompts: what I do now, what relevant evidence I can explain, and why this role makes sense next. Use your own details. Don’t memorise a stranger’s answer.
2. “What are your weaknesses?”
This is a question about self-awareness and what you do with it. Pretending you have no weaknesses is unlikely to make the conversation useful. Neither is dressing up a strength as a weakness and hoping nobody notices.
Choose a real area you are working on. Explain when it matters, what you have changed and what you have learned. If you can show improvement, be specific about the evidence. If it is still a work in progress, say so.
Read the requirements of the job before preparing this answer. Don’t disguise a gap in an essential skill as a harmless quirk. Be clear about what you can currently do and where you would need training or support. The interviewer needs an accurate picture, particularly where the work carries technical or safety responsibilities.
You don’t need to finish by claiming that another strength cancels the weakness out. Show that you understand it and are taking responsibility for dealing with it. My longer article on answering the weakness question goes further into that conversation.
3. “Why are you leaving your current role?”
Be honest, but keep the answer professional. Explain the reason for considering a move and what you are looking for next. Don’t turn it into a running commentary on everything wrong with your current employer.
If the reason is progression, explain what progression means to you. If it is the work, location, package or working pattern, be clear about that. Then check that the vacancy you are discussing actually offers the change you want.
If your role ended through redundancy or a company closure, explain that plainly. There is no need to invent a career-development story to make it sound more impressive. Keep your answer consistent with your CV and the employment timeline.
Avoid praising a company’s innovation, reputation or growth unless you have a reason for saying it. Talk about what you have found out, what you still need to understand and why the role could be a sensible next move.
Build an answer book, not a script
Practise with friends or family and build an answer book. Keep notes of relevant work, your contribution, the outcome and what you learned. Use accurate figures where you can support them; don’t add a percentage because you think an answer needs one.
Practise saying the answers out loud. Can you get to the point? Can you explain the detail if asked? Can someone understand what you did without knowing your current company’s terminology?
Use the interview-preparation guide in the Candidate Resource Pack to organise the wider preparation. If the interview is for a technical sales role, read how salespeople can sell themselves in interviews as well.
You are not trying to win a competition for the slickest answer. You are trying to help both sides work out whether you can do the work and whether the move makes sense.
