Interview Blueprint
Role-specific preparation roadmaps built from real hiring patterns at top US and UK employers. From algorithm interviews to salary negotiation scripts — everything you need to land the offer.
Use STAR for every behavioral question: Situation (set the context in 1–2 sentences) → Task (what was your responsibility) → Action (what YOU specifically did, not the team) → Result (measurable outcome: %, $, time saved). Quantify the result even if estimated.

Frequently Asked Questions
What is the STAR method for interviews?
STAR stands for Situation, Task, Action, Result. Use it to answer every behavioral question with a specific, quantified story from your past. Aim for 2–3 minutes per answer. Always end with a measurable result ("reduced latency by 40%", "increased conversion by 12%").
When should I negotiate salary in the interview process?
Wait until you have a written offer. Never negotiate in early screening rounds. Once you have the offer: take 24–48 hours, research the market, and send a polite counter via email so it's documented.
How many rounds do FAANG/Big Tech interviews have?
Typically 5–7 rounds: 1 recruiter screen, 1–2 technical phone screens, then 3–5 virtual onsite loops (2 coding, 1 system design, 1–2 behavioral). Total time from application to offer: 4–8 weeks at most companies.
What questions should I ask the interviewer?
Strong questions: "What does success in this role look like at 30/60/90 days?" — "What's the team's biggest technical challenge right now?" — "How does the company support career growth?" — "What do you enjoy most about working here?" Avoid asking about salary or perks in early rounds.
