Opening questions

1. Walk me through your background as a full stack developer.

   Keep it to 90 seconds, newest first, and end on why this role. Name Frontend Development and Backend Development early — if they're in the posting, they're on the interviewer's checklist, and this answer sets the agenda for the rest of the conversation.

2. Why are you interested in this full stack developer position?

   Connect one specific thing about the company or team to your own track record — a product, a market, a way of working. Generic praise reads as a mass application; specificity reads as intent.

3. What does success look like in your first 90 days as a full stack developer?

   Structure it as learn, contribute, own: understand the team's current Frontend Development setup first, ship something small by week four, and name the area you'd want to own by month three. Asking what THEY consider success is a strong closing move.

4. Why are you leaving your current role?

   Keep it forward-looking and under 30 seconds — what you're moving toward, not what you're escaping. Any negativity about a current employer gets projected onto how you'd talk about this one.

Role-specific questions

1. Tell me about a feature you built from database to UI.

   Walk the full path — schema choice, API shape, client state, deployment. Interviewers listen for whether the layers were designed together or bolted on, and for one place where a front-end need changed a back-end decision.

2. Where do you choose to go deep, and where do you accept 'good enough'?

   This tests judgement about the breadth trade-off. A strong answer names a specific area you invest in (say, data modelling) and one you deliberately keep simple, with the reasoning behind each.

3. How have you used Frontend Development in a recent project? Walk me through one example.

   Use STAR and end on a number — a percentage improved, hours saved, error rate cut. Mention the tools involved (JavaScript, TypeScript) by name; concrete stacks are what separates practitioners from keyword-matchers.

4. Tell me about your experience with JavaScript.

   Go deeper than "I've used it for X years." Describe one thing you built or ran with JavaScript, one limitation you hit, and how you worked around it — knowing a tool's edges is stronger evidence than fluency claims.

5. How do you keep your Backend Development work accurate when you're under time pressure?

   Name your actual quality mechanism: checklists, peer review, a verification pass, automation. Then give one example where the mechanism caught something a rushed pass would have shipped.

6. How would you explain REST APIs to someone outside the field?

   This tests communication, not knowledge. Use one everyday analogy, keep it under a minute, and skip jargon entirely — the interviewer is imagining you in front of a stakeholder or a new teammate.

7. How do you stay current with engineering practices and tools?

   Name real sources — specific newsletters, communities, or practitioners — and finish with one thing you learned recently and actually applied. The applied half is what makes the answer credible.

Behavioural questions

1. When have you changed your mind about something important at work?

   Name the position you held, the evidence that moved you, and what you did publicly about the reversal. Interviewers are testing whether new information updates your view or just gets argued with.

2. Tell me about someone difficult you had to work with successfully.

   Avoid character assassination; describe the specific friction and what you changed in your own approach. Interviewers listen for whether you adapted or simply waited them out.

3. Tell me about the last thing you taught someone.

   Concrete beats abstract — what they couldn't do before, how you taught it, and whether they can now do it without you. This question surfaces whether you scale knowledge or hoard it.

4. Describe a time you missed a deadline or a project failed. What happened?

   Choose a genuine miss and own it without blaming others. Spend one sentence on what went wrong and three on what you changed afterward — the process fix is the answer; the failure is just the setup.

5. Give an example of leading or influencing others without formal authority.

   Describe how you built the case — data, a small proof of concept, or early allies — rather than relying on escalation. Quantify what changed after people came along; influence without a title is a seniority signal.
