Insights on cloud architecture, software development, system design, interview prep, and lessons from building with partners and customers.
A practical order for stacking AWS certs so each one builds on the last instead of forcing you to relearn the basics.
Statistics rounds decide data science, analyst, ML and quant interviews, and they are rarely about formulas. Fifty real questions on probability, distributions, hypothesis testing, regression and causal inference, with worked answers and the traps interviewers set.
Object-oriented programming questions open almost every language round and decide most low-level design rounds. Fifty real questions on the four pillars, SOLID, composition, and the design patterns interviewers actually probe, with code and the follow-ups.
Operating system questions are how interviewers find out whether you understand what your code is actually doing: processes, threads, scheduling, locks, virtual memory and I/O. Fifty real questions, with the follow-ups and the production scenarios that come next.
Networking questions show up in backend, SRE, DevOps, cloud and security loops, and the interviewer never stops at the definition. Fifty real questions on the OSI model, TCP, DNS, TLS, HTTP and debugging, with the follow-ups that come next.
A practical look at the AWS Certified Data Engineer Associate cert, who it actually helps, and how to study for it without wasting time.
An honest breakdown of the AWS CloudOps Engineer Associate exam (SOA-C03), the replacement for SysOps Administrator: what changed, what each domain really tests, and how to study for it.
An honest look at why the AWS Advanced Networking Specialty exam earns its reputation and how to prepare for it without wasting months.
SDET interviews test whether you can think like a tester and build like a developer at the same time. Fifty real questions, from the test pyramid to flaky CI failures, with Playwright code and the follow-ups interviewers actually ask.
Spring Boot is the default stack behind most Java backend roles, and interviewers use it to separate people who use annotations from people who know what the annotations do. Fifty real questions, with the gotchas that come up in live rounds.
ML engineer and data scientist loops test the fundamentals - bias-variance, leakage, metrics, trees, backprop - before they get to system design. Fifty real questions, with the answers and the follow-ups interviewers ask next.
Data analyst loops test four things - SQL, spreadsheets, statistics and judgment - and most candidates over-prepare the first and under-prepare the last. Fifty real questions with answers, SQL included, from joins to take-home cases.
Solutions architect loops test two things at once: can you design a sound system, and can you get a customer to agree to it. Fifty real questions, from discovery and the 7 Rs to RAG cost per request and the customer who wants the wrong thing.
A TPM loop tests whether you can land a multi-team program on a real date without hiding the bad news. Fifty real questions, from scoping and dependencies to slipping dates, migrations and stakeholder fights.
PM loops test judgment, not vocabulary. Fifty real product manager interview questions - product sense, metrics, prioritization, estimation, AI products and behavioral - each with a structure and a worked example.
System design rounds ask you to draw boxes; distributed systems questions ask what happens when the boxes stall, lie and disagree. Fifty real questions on consistency, consensus, clocks and failure modes, with the follow-ups interviewers push on.
DynamoDB rounds are modelling rounds in disguise: the interviewer wants to see you start from access patterns, pick keys that spread load, and know which limit bites first. Fifty real questions, with the gotchas.
AWS networking is where cloud interviews separate people who have clicked through a console from people who have debugged a broken route table at 2am. Fifty real questions on VPCs, routing, endpoints, hybrid connectivity and DNS, with the follow-ups interviewers ask next.
Lambda rounds are not about whether you can deploy a function. They are about whether you know what happens when it is throttled, retried, or handed the same message twice. Fifty real questions, with real answers.
AWS CDK rounds are less about syntax and more about what happens to your deployed resources when the code changes. Forty real questions, from constructs to the cross-stack deadlock, with the follow-ups interviewers ask next.
A practical look at who the AWS Security Specialty is actually for, what it tests, how to study, and the on-the-job edge it gives engineers.
The C# and .NET questions that actually come up in 2026 interviews - value types, records, async/await, DI lifetimes, EF Core, and .NET 10. Real answers with code, not textbook definitions.
Azure interviews in 2026 lean hard on identity, networking, and governance - the places where enterprise Azure estates actually break. These are the 50 questions that come up, with answers that show real judgment.
A practical study plan for the AWS DevOps Engineer Professional exam, covering prerequisites, the topics that actually carry weight, and how to prep without wasting weeks.
An honest look at who the AWS Solutions Architect Professional cert actually helps, who should skip it, and how to study for it without wasting months.
An honest breakdown of what the AWS SysOps Administrator exam covers, who it's for, and how to study for the parts people fail.
A practical week-by-week plan for passing the AWS Developer Associate exam, built around the services and skills the test actually checks.
A practical guide to passing the AWS Cloud Practitioner cert quickly and why it is worth the few weeks it takes.
How behavioral interviews change at the senior level and the kind of stories and judgment that actually get you the offer.
How to choose a failure story for a behavioral interview that shows judgment and growth without tanking your candidacy.
