Walk Into Every SWE Interview Knowing What You'll Say
Senior SWE interviews have three distinct rounds most candidates prepare for separately: coding, system design, and behavioral. The candidates who convert most consistently are the ones who integrate preparation — their system design examples come from their behavioral stories, and their behavioral stories show up in coding discussion context. Preparation is a system, not a checklist.
Prepare 5-7 technical stories that pull double duty — they work in system design, behavioral, and coding discussion rounds. Rehearse the narrative, not the answer.

The playbook
Five things to do, in order.
Build a technical story bank
5-7 projects where you can speak to: the problem, the constraints, the technical decision you made, the tradeoffs, and the outcome. These stories need to be drill-down ready — interviewers will probe any claim you make.
Prepare for the coding round specifically
LeetCode Medium is the real bar for most FAANG-adjacent companies. Focus on graphs, trees, and dynamic programming patterns. But more importantly, practice talking while coding — most candidates code silently and lose.
Practice system design out loud, not on paper
Do 10 system design problems from scratch, on video, talking to yourself or a partner. The difference between knowing a design and being able to present it under pressure is enormous.
Prepare "tell me about yourself" as a 90-second narrative
Where you've been → what you've built → what you're known for → why this role. Rehearse until it's smooth. It sets the frame for the entire interview.
Research the company's engineering blog and recent hiring bar
Companies' engineering blogs show what problems they're solving. Candidates who reference specific engineering challenges in interviews are remembered.
See the transformation
"I worked on a microservices project where we improved performance."
"I led the migration of our payment processing service from a monolith to an event-driven microservices architecture. The constraint was 99.9% availability SLA during migration. I chose blue-green deployment to eliminate downtime risk, ran parallel processing for 2 weeks before cutover, and achieved zero downtime with a 40% latency improvement."
Questions people ask
How much LeetCode do I need?
100-150 Mediums covering core patterns is enough for most senior roles. Doing 500+ problems without reviewing patterns is diminishing returns.
How do I prepare for system design if I haven't built distributed systems?
Read engineering blogs from Stripe, Netflix, Uber, Discord. Understand the problems they solved and why. You can reason about systems you haven't built if you understand the tradeoffs.
