Give a tight 60–90 second pitch, not your life story. Structure: present (current role + core stack) → past (one or two relevant achievements with impact) → future (why this role fits your next step).
A structure for behavioural answers: Situation (context) → Task (your responsibility) → Action (what YOU did) → Result (the outcome, ideally quantified).
Stay positive and forward-looking: frame it as seeking growth — bigger scope, new tech, more ownership, or a domain you care about. Never bad-mouth your current employer or manager; it reads as a red flag.
Strength: pick one relevant to the role and back it with a concrete example. Weakness: give a real, non-fatal one plus what you're actively doing to improve it — this shows self-awareness, which is the actual thing being tested.
Use STAR. Pick a genuinely hard problem, explain how you diagnosed it (not just the fix), the tradeoffs you weighed, and the measurable result. Show your debugging process and reasoning — that's the point.
Show maturity: describe the disagreement neutrally, how you listened to their view, focused on the shared goal/data rather than ego, and reached a resolution. Emphasise the working relationship afterwards.
Show you can push back respectfully with evidence (data, prototypes, tradeoffs), but also that you can disagree and commit once a decision is made. Balance conviction with being a team player.
Describe your system: prioritise ruthlessly (impact vs effort), communicate risks early, break work into increments, and negotiate scope rather than silently missing dates. Give a concrete example where this worked.
Pick a real mistake, own it without blaming others, explain the impact, how you fixed it, and — most importantly — the lesson and how you changed your process so it won't recur.
Be specific: docs/changelogs, newsletters, following core-team members, side projects, reading source, communities. Mention something recent you learned and applied (e.g. Angular Signals) to prove it's real, not a script.
Describe something you drove beyond your assigned tasks — improving a slow build, adding tests, refactoring a fragile module, mentoring — where you saw a problem and acted without being told. Quantify the impact.
Frame feedback as a gift: you separate ego from the code, ask clarifying questions, apply what's valid, and discuss respectfully where you disagree. Give an example where feedback improved your work.
Show ambition that aligns with the company: growing technical depth (senior/architect) or breadth (leading features/mentoring). Avoid over-specific titles or anything that signals you'll leave quickly. Tie it to growing here.
Map your strengths directly to the role's needs from the job description: relevant skills, a track record of impact, and culture/attitude fit. Be confident and specific, not generic.
Research the market range for the role/location/experience first. Give a range grounded in that, state it's negotiable based on the total package, and where possible let them anchor first. Never undersell without data.
State your actual notice honestly and add that you're flexible where possible (buy-out, negotiating an early release). Being straightforward here builds trust for the offer stage.
Always say yes — it signals genuine interest. Good questions: the team's biggest technical challenge, how success is measured in the first 6 months, the codebase/testing culture, how decisions get made, and growth/mentoring paths.
Describe the disagreement objectively, explain how you listened to the other person's perspective, shared your reasoning with facts or data, and worked together to reach a solution. Focus on collaboration and the positive outcome rather than who was right.
Explain how you prioritized the most important work, communicated risks early, broke the task into smaller milestones, and successfully delivered the feature or agreed scope. Mention how you maintained quality despite the deadline.
Choose a project that closely matches the role you're applying for. Explain the business problem, your specific contribution, the technologies you used, the challenges you solved, and the measurable impact on users or the business.
Explain how you evaluated the new priorities, discussed the impact with stakeholders, reorganized your tasks, and adapted without losing focus on the team's goals. Demonstrate flexibility and clear communication.
Describe the situation, why the technology was needed, how you learned it using documentation, tutorials, or mentoring, how you applied it in the project, and the successful outcome. Emphasize your ability to learn independently.
