Book Description
Develop the skills that matter most in modern software engineering by combining real-world system design with structured behavioral intelligence, the technical and human strengths that carry you through your work and your career.

You start with the foundations, distributed systems, networking, scalability, security, databases, and architecture patterns, then work through full design walkthroughs, from a real-time bidding platform to an agentic AI system for investment research, weighing the trade-offs that shape real systems: performance, reliability, and availability, plus observability and the tools reshaping design in the AI era.

On the behavioral side, you move beyond memorized answers. Turn real work into high-signal stories with STAR+R and a lasting story bank, speak the language of delivery and stakeholders through DORA and RACI, and learn the scorecard interviewers use to evaluate you. You also get guidance for Big Tech interviews, AI-assisted preparation, and strategies from technology leaders Shalini Goyal and Alok Sharan.

By the end, you will approach both system design and behavioral interviews with confidence, communicate your decisions clearly, and show the technical and leadership qualities modern engineering demands.
