Your Intro + Delivery Mechanics
The 60-second "tell me about yourself", the delivery habits that matter more than content, and what each round is really testing.
01The 60-second "tell me about yourself"
Trim to 30s by cutting the second halves of each part. Practice until it's conversational, not recited.
02Delivery mechanics (matter more than content)
2 seconds of thought reads as depth, not slowness.
"About two million requests a month" — not proudly, just factually.
"Two things here — first… second…" Interviewers remember structured answers.
"I haven't used X in production — my mental model is Y; here's how I'd verify." This scores HIGHER than a bluff at every good company.
Land the result, stop talking. Silence after a strong finish is the interviewer's problem, not yours.
Restate the problem → tiny example → brute force out loud → optimize → code → trace through the example → state complexity. Every time, same ritual.

04Round-type cheat sheet
| Round | What they're really testing | Your play |
|---|---|---|
| DSA / coding | Can you reason out loud + pattern-match | The ritual above; patterns cheatsheet |
| CS fundamentals | Do you understand what you use daily | Answer from production experience first, theory second |
| System design | Structured thinking + tradeoffs | The framework; steer to LLM-gateway/Kafka designs you run |
| Behavioral | Ownership + honesty + growth | Story bank; never inflate |
| "Any questions?" | Whether you think like an owner | Ask "what breaks most often?" |
