Software Engineer Interview Prep Podcast

"Design the backend for Twitter." Reciting HTTP verbs won't get you through that whiteboard session. In this deep dive we build a complete, staff-level blueprint for REST API design: the reasoning behind every rule, the trade-offs interviewers probe, and the patterns that keep large systems evolving safely. You'll learn: - Fielding's six REST constraints, and why statelessnes...

Your connection drops mid-checkout on a $1,000 ticket. Do you hit refresh and risk paying twice? The answer lives in the invisible architecture of REST APIs. In this deep dive we go from the basic grammar of the web to the patterns that keep global platforms fast, safe and reliable. You'll learn: - What REST really is, and why verbs never belong in your URLs - Resource naming, the two-level nestin...

"Walk me through what happens from kubectl apply to the first request hitting your container." It sounds like a warm-up question, but how you answer it can decide whether you land a senior or staff role. In this deep dive we trace a pod from creation to production and unpack the failure modes interviewers expect you to anticipate. You'll learn: - The full startup chain: API server, e...

Senior system design interviews don't test whether you know what a load balancer is. They test how you think under pressure: how you handle ambiguity, weigh brutal trade-offs and defend every box you draw. In this deep dive we unpack the framework used to evaluate senior engineers, architects and principal candidates. You'll learn: - The RADIO framework (Requirements, API, Data model, Infr...

A single misconfigured setting in Kafka doesn't just slow a page down. It can silently vaporize financial transactions. In this deep dive we walk through real production failure scenarios and the exact reasoning interviewers look for in staff-level system design interviews. You'll learn: - Why acks=1 loses data, and the four configuration layers for zero data loss - Consistency vs availabi...

Why does a chat message arrive instantly, but the web was never built for it? In this deep dive we unpack WebSockets: how engineers turned a request/response web into an open, two-way line, and what that costs at scale. You'll learn: - Why short polling, long polling and Server-Sent Events fall short (and the math behind 200,000 empty requests per second) - How the WebSocket handshake hides in...

The mental model and the toolkit come together here. We cover managing a session in real time — when to course-correct, when to clear and restart — the five failure patterns that quietly tank your work and how to fix each, and a complete worked problem run end to end: explore, plan, implement in a fresh session, verify with tests, and review with an adversarial subagent. Plus scaling techniques an...

This is where the deep technical interview questions live. Claude Code has five extension points — CLAUDE.md, skills, hooks, subagents, and MCP — and knowing which to reach for is a core competency. We break down each one: why CLAUDE.md is always-on context you must keep lean, how skills load knowledge on demand and why the description field decides everything, when hooks give you deterministic gu...

The Agentic Mental Model: what "agentic" means and the loop, the context window as the governing constraint, explore→plan→implement→commit, verification, and precise prompting. Most engineers meet AI coding tools as a smarter autocomplete. Claude Code is something else: an agent that explores, plans, and writes code on its own while you direct and review. This opening episode rewires how...

SEASON 1 — "The Shift" Listen to - S1E1 Interview an engineer who transitioned from backend → AI engineer. Their story IS the season premise.

The behavioral round quietly decides more FAANG loops than coding or system design — and most engineers spend 300 hours on LeetCode and 45 minutes preparing for it. In this deep dive, we unpack: – Why FAANG weights behavioral signal so heavily (leveling, risk, culture fit)– The STAR framework, dissected letter by letter, with the failure modes at each step– CARL and why the Learning layer is the p...

Every scenario includes: Real-world context setting the stage The interview question as it would be asked A structured model answer Exact configuration parameters with values and reasoning

Design a batch processing system for end-of-day payment settlement at a payments company that processes 50 million transactions per day . The system must net merchant positions, calculate fees, and initiate fund transfers to merchant bank accounts within a strict bank cutoff window. Walk me through your design, covering reliability, scalability, and how you'd handle failures. Key Takeaways The...

When I run kubectl apply, the request is sent to the Kubernetes API Server , which acts as the entry point to the cluster. The API Server processes the request through several stages: Authentication – validates the client (certificates, tokens, etc.) Authorization – checks permissions using RBAC Admission Controllers Mutating (e.g., inject defaults, sidecars) Validating (ensure request is complian...

What We Cover in This Episode: The Probe Trap, Why telling an interviewer that a "liveness probe failure removes traffic" is an instant red flag (it actually kills and restarts the container!), and why you should never check external databases in your liveness probes. The JWT Myth: Why saying "JWTs are encrypted" will cost you points. We explain how to articulate that standard...

HTTP Contracts & Status Codes: The podcast will cover why returning a 200 OK for an error is a massive anti-pattern. Jenny explains the exact contract of 2xx, 4xx, and 5xx status codes, and emphasizes the use of trace IDs and machine-readable error envelopes so clients know exactly what went wrong and how to fix it. Versioning & Pagination: They will discuss the trade-offs of URI, Header,...

Are you preparing for a senior security or backend engineering interview and struggling to articulate how to secure microservices in a zero-trust environment? In this deep dive, we break down the definitive guide to OAuth 2.0, OpenID Connect, and advanced token security to help you move beyond textbook definitions and start designing banking-grade architectures. Whether you are designing a Backend...

JVM Architecture Overview — runtime data areas, memory model, flag reference table Class Loading Subsystem — delegation model, loading phases, JPMS/Jigsaw module system Execution Engine & JIT — tiered compilation levels (0→4), inlining, escape analysis, loop vectorisation, SIMD intrinsics, speculative optimisation and deoptimisation Garbage Collection Algorithms — deep dives on G1, ZGC (colour...

Mastering REST API Design & Best Practices Are you struggling to articulate the exact difference between a basic API and a production-grade, evolvable API during system design interviews? In this deep dive, we break down the 10 pillars of REST API design to help you move beyond simple CRUD operations and start building like a Senior Engineer. What We Cover in This Episode: The Richardson Matur...

Episode Description: Mastering Heaps & Priority Queues Are you struggling to recognize exactly when to use a Priority Queue in your coding interviews? In this deep dive, we break down the Heap data structure from the ground up to help you stop memorizing solutions and start recognizing the core algorithmic patterns. What We Cover in This Episode: The "Flat Tree" Secret: Discover how...

The Sliding Window Algorithm is a powerful technique used to reduce the time complexity of problems involving arrays or strings—specifically those that require finding a sub-segment that meets certain criteria. Instead of using nested loops O(n^2), the sliding window maintains a dynamic range that "slides" across the data, usually bringing the complexity down to O(n). Problem:Find the ma...
