Interview Questions and Sample Answers (2026 Guide)

Most interview questions are predictable. The same 15-20 questions come up again and again — only the emphasis changes with the company and role. In this guide we've gathered the most common questions, a sample answer for each, and the traps to avoid.

Answering Strategy: The STAR Method

Answer every experience-based question using the STAR method:

• Situation: the context (15-20 seconds)
• Task: your responsibility (10 seconds)
• Action: the concrete steps you took (30 seconds)
• Result: the outcome, with numbers (15 seconds)

Total: ~70-90 seconds. Longer than that bores them; shorter feels superficial.

10 Classic Questions and Sample Answers

1. "Tell me about yourself."

The first question, and the one most people answer badly. Don't tell your life story — tell your professional arc.

"I graduated in software engineering five years ago. For the first two years I wrote backend code at an enterprise bank — that's where I learned how payment systems scale. Over the next three years I grew as the sole backend engineer at a SaaS start-up: we scaled to 50,000 users and closed a seed round in Q2. Now I'm looking for a staff-level role, because I want to move into team-building and technical leadership — and this position is exactly that direction."

Trap: Don't mention where you were born. Don't list hobbies. Don't recite your CV out loud. Speak for 60-90 seconds, then stop.

2. "Why this role / company?"

Here the interviewer wants to see that you've researched the company, prepared, and aren't applying at random. Say three things: something about the company + something about the role + your own goal.

"Three reasons. One: I've used your product for a year — the UX decisions in the analytics module you shipped recently are excellent, and I'd love to join a team working to that standard. Two: the advert mentions an 'async, distributed team culture' — that's exactly the way I work best. Three: my career goal is to deepen my experience of scale in B2B SaaS; I've built a product with 50,000 users, and your scale of 500,000 is the ideal next step."

3. "What is your greatest achievement?"

The mediocre candidate says "I did a bit of everything." You should pick one specific achievement and tell it with STAR.

"Last year in Q3 the company's payment service had a 12-hour outage caused by a race condition. It wasn't my responsibility, but two months after joining the team I ran the root cause analysis and redesigned it using the saga pattern. The next six months saw zero outages, and deployment frequency went from once a week to four times a day. What I'm proudest of: we reached the solution by agreement with the whole team — it was a team outcome, not a 'hero' moment."

4. "What is your greatest weakness?"

The most badly answered question. Don't say "I'm a perfectionist" — it's a cliché. Name a genuine weakness and explain how you manage it.

"I used to struggle to say no — I'd say yes to every request and then get overwhelmed. Last year, working with a mentor, I started using a priority matrix: a five-minute ritual where I ask of each new request, 'now or later, me or someone else?' Is it completely solved? No — but I no longer burn out the way I used to, and over the last six months my manager has felt far less need to check in on me."

5. "Where do you see yourself in five years?"

Grand statements like "I'll be CEO" are a trap here. Be realistic but ambitious.

"In five years I want to be in either a staff-engineer or an engineering-manager role — I haven't decided which yet. That's why it matters to grow long-term with a company where I can try both. A company going through the seed-to-Series-B stage, like yours, keeps both paths open — that's one of the reasons I want to start here."

6. "Why are you leaving your current job?"

Bad-mouthing your old company is catastrophic. Reframe it as a positive "why here".

"I've learned a great deal over three years at my current company, but the product has stabilised — there are fewer new technical challenges now. I still want to be part of the 'zero to scale' journey, and your team, going through Series B, is exactly that."

7. "What are your salary expectations?"

If you're early in the process, give a range; later on, give a single figure. Always aim slightly high.

"Based on my market research, the range for a mid-senior backend engineer is around £65,000-£80,000. As I want to make a long-term contribution to your team, I'm aiming for £75,000, but I assess the whole package — benefits, equity, learning budget — as a package."

8. "Do you have any questions?"

The answer to this is never "no". Bring 3-4 prepared questions and ask 2 of them. Ideal questions:

• "What would success look like in the first 90 days for whoever takes this role?"
• "What is the toughest technical decision the team is facing right now?"
• "What keeps you (the interviewer) here?" (personal but powerful)

9. "What do you know about us?"

A preparation test. Say three things: (1) product, (2) recent news, (3) market position.

"You're a B2B SaaS analytics product, focused particularly on the e-commerce segment. You announced Series B last month — $12M raised. What sets you apart from competitors is your 'no-code' analytics dashboards — that's the UX angle that differentiates you from larger rivals."

10. "Describe yourself in three words."

The ordinary "ambitious, team player, hard-working" answer buries you. Pick three unusual but accurate words + one line of explanation each.

"Systematic — I make decisions with data and frameworks, I don't rely on gut feeling. Patient — especially in code review, I'll spend 30 minutes explaining something to a junior, and then see correct code for the rest of my life. Curious — over the last six months I learned Rust; I don't even use it, but the 'low level' opens up my thinking."

5 Traps in Behavioural Questions

1. "We did it" — what did you do? The interview is assessing you; the team's success isn't yours. Don't start with "we"; be concrete with "I took this step."
2. Don't answer hypothetically. Instead of "if such a situation arose I would do X", say "last year this happened and I took this step."
3. Don't speak negatively. Negative comments about a former colleague, manager or company are a red flag.
4. Filler words. "So", "like", "actually" — you'll say them 50 times without noticing. Practise and record yourself.
5. Dodging the question. Don't give the answer you prepared instead of the one asked. Listen to the question, then answer.

Preparing for Interviews with AI

Memorising ready-made template answers is now an outdated method. An AI interview coach (for example the CVLayer Interview Coach) can:

• Generate 30+ role-specific questions
• Take your answer as audio and give AI feedback
• Count filler words (um, er, like)
• Score how well you follow the STAR method
• Give pronunciation feedback for English-language interviews

Far more effective than talking to a mirror on your own.
