Structure your answer: Present — Past — Future. Start with your current role, touch on 1–2 relevant past experiences, and close with why you're excited about this opportunity. Keep it under 90 seconds and tailor it to the job description.

Pick 2–3 strengths that align with the role (e.g., problem-solving, leadership, data-driven decision-making). Back each one with a brief real example. Avoid generic traits like "hardworking" — be specific.

Choose a genuine weakness that is not a core requirement of the role, then explain the concrete steps you're taking to improve it. The key is to show self-awareness and a growth mindset — e.g., "I used to struggle with public speaking, so I joined Toastmasters and now lead weekly stand-ups."

Show you've done your homework. Mention something specific about the company — their product, culture, recent news, or mission — and link it to your own values and career goals. Never say "I need a job."

Use the STAR method: describe the Situation, the Task, the Action you took, and the Result. Focus on communication, empathy, and finding common ground. End with the positive outcome or lesson learned.

Own the failure without deflecting blame. Explain what went wrong, what you learned from it, and how you changed your approach afterward. Employers value humility and the ability to grow from setbacks.

Highlight collaboration, not just your individual contribution. Describe how you leveraged each team member's strengths, handled differing opinions, and delivered a result greater than what any one person could achieve alone.

Key considerations: Use a hash function (e.g., Base62 encoding) to generate short keys, store mappings in a distributed database (Cassandra or DynamoDB), handle redirects with HTTP 301/302, implement caching with Redis, and plan for rate limiting and analytics tracking.

REST uses fixed endpoints per resource and can lead to over-fetching or under-fetching data. GraphQL lets the client specify exactly what data it needs via a single endpoint, reducing payload size. REST is simpler to cache; GraphQL excels for complex, nested data requirements.

O(log n). Binary search repeatedly divides the search interval in half. After each step, the search space shrinks by a factor of 2, so the number of steps needed is the number of times you can halve n until you reach 1 — which is log₂(n). Requires a sorted array.

Deflect early in the process. Say "I'd like to learn more about the role and total compensation package before discussing numbers." If pushed, give a researched range (use sites like Levels.fyi, Glassdoor, Blind) — e.g., "$120K–$140K depending on the full package." Never give a single number first.

Total compensation matters. Consider: equity/RSUs, annual bonus (target %), signing bonus, 401K match, remote flexibility, learning budget, PTO, health benefits, and stock refresher policies. A lower base with strong equity and benefits can often outperform a higher base elsewhere.

Negotiate collaboratively, not confrontationally. Express enthusiasm first, then frame requests around market data and your value — e.g., "I'm very excited about the role. Based on my research and experience, I was hoping we could revisit the base salary." Have competing offers as leverage if possible. Be reasonable (10–20% above initial offer is typical).
