How to answer common interview questions

Most interviewers ask behavioural questions: what did you do in a real situation, not what would you do in theory. Large employers such as the City of Calgary say so directly on their interview method page. If you can tell a clear, specific story, you can handle most of what comes your way.

This guide covers the story method, eight questions that come up again and again, the tough ones, and what to ask at the end.

Answer with the STAR method

STAR is a four-part story. The City of Calgary describes it the same way:

Situation: what was going on, in one or two sentences.
Task: what needed to happen, and your part in it.
Action: the specific steps you took. Spend most of your time here.
Result: how it turned out, with a number if you have one.

The action is what interviewers score, because it shows how you will handle the next problem. Say "I", not "we". Work, volunteer work and school projects all count.

Example. Question: Tell me about a time you had to learn something quickly.

"Our store switched to a new inventory system the week before a big sale (situation). I had to train two new hires on it, and I had only used it for a day (task). I stayed after my shift to work through the training guide, made a one-page cheat sheet of the five screens we used most, and had each new hire practise on real returns (action). Both were working on their own by Friday, and we had no stock errors during the sale (result)."

Eight questions you will almost certainly get

The sample answers are examples of shape and length. Use your own details.

1. Tell me about yourself. They want a 60 second pitch, not your life story. Give your current role, one or two relevant strengths, and why this job is the next step.

"I'm a customer service lead with five years in retail, the last two running a team of eight. I'm good at keeping people calm when things go wrong and at training new staff quickly. I'm looking for a role with more responsibility, and this one is a step up in exactly that."

2. Why do you want this job? They want to know you picked them on purpose. Name something specific about the role or the employer, and connect it to what you do well.

"I've followed your expansion into the south side, and I like that new hires get proper training. I'm strongest at onboarding people, so I'd contribute from the first month."

3. What are your strengths? Pick two that matter for this job and back each with proof. Avoid a list of adjectives.

"Organization and follow-through. At my last job I cut our weekly scheduling errors from about six to one by building a shared calendar the whole team used."

4. Tell me about a time you handled a conflict. Use STAR. They want to see that you listen, stay professional, and fix the problem, not that you won.

"Two coworkers disagreed about who covered weekend shifts (situation). As the lead I needed a fair solution before the next schedule went out (task). I spoke with each of them separately, then proposed a rotating weekend schedule and asked for feedback (action). Both agreed, and we had no weekend shift disputes for the next six months (result)."

5. Tell me about a mistake you made. Pick a real but modest one. Spend most of your answer on the fix and what you changed afterward.

"I once sent a customer the wrong quote. I called them the same day, apologized, sent the correct one, and then added a second-person check to our quote process. We haven't had a wrong quote since."

6. How do you handle pressure or tight deadlines? Give a specific example with the steps you took to prioritize.

"During year-end, I had three reports due in two days. I listed what each report depended on, finished the one blocking others first, and told my manager early that the third would arrive the next morning. All three were delivered, and the late one only by half a day."

7. Why should we hire you? This is a summary of questions 1 to 3. Match your best strength to the biggest need in the job posting.

"You need someone who can step in quickly and keep customers happy. I've done that for five years, I've trained new staff, and I can start contributing right away."

8. Where do you see yourself in five years? They want to know you will not leave in six months. Be honest and keep it tied to the field, not to this exact title.

"I want to keep growing in operations, ideally leading a small team. I'd like to learn the business here first and earn that responsibility."

The tough ones

These feel risky, but the formula is simple: be honest, be brief, and end on something positive.

What is your biggest weakness? Name a real weakness that does not sink the job, then show what you are doing about it. "I work too hard" reads as a dodge.

"I used to avoid delegating because I wanted things done right. I now hand off one task a week with clear instructions, and it has freed up about three hours a week."

Why did you leave your last job (or why are you leaving)? Never criticize a past employer. Talk about what you are moving toward.

"I learned a lot there, but there was no room to grow into a lead role, and that's what I want next."

Can you explain this gap in your resume? State it plainly in one sentence, then move to what you are ready for. You do not owe a long story.

"I took eight months to care for a family member. That's settled now, and I've kept my certification up to date and I'm ready to get back to work."

What are your salary expectations? If the posting lists a range, say you are comfortable within it. If not, give a researched range and say you are flexible for the right role. Check what similar postings pay before you answer.

"Based on similar roles, I'm looking for something in the range of $X to $Y, and I'm open to discussing the full package."

Questions to ask them

You will almost always be asked if you have questions. Having two or three ready shows you are serious about the job.

What does success look like in the first 90 days?
What would a typical week look like in this role?
What do you like most about working here?
What are the next steps, and when should I expect to hear back?

Skip pay and vacation until they raise it or make an offer, unless the posting leaves the pay out entirely.

Mistakes that cost people the job

Rambling past two minutes on one answer.
Answering with "we" so the interviewer cannot tell what you did.
Speaking badly about a former boss or coworker.
Having no questions for them.
Not knowing what the company does.
