Boeing full-stack interview that leaned heavily into AWS and DevOps fundamentals. Nothing wildly unexpected but the drill-down questions on practical scenarios kept it from being a simple recitation exercise.

Walk me through how you'd design a VPC, including subnet layout, route tables, and how NAT and internet gateways fit in.
How do S3 pre-signed URLs work, and when would you use them for uploads versus downloads?
How do you apply least-privilege principles across IAM roles, policies, and service-to-service permissions?

“I started with public vs private subnets and worked outward from there.”

Did a coding round for a full-stack role at Boeing. Just one algorithmic problem, nothing too wild, but the kind of thing you either know the two-pass trick for or you don't.

Given a string, find the index of the first character that appears only once. Return -1 if no such character exists.

“Pretty standard frequency-count problem.”

React hooks deep dive for a Full-stack Engineer role at Boeing. The whole session was discussion and short-answer style, no live coding, just them probing how well you actually understand what's happening under the hood with hooks.

How does useState work, and what happens to state across re-renders?
Walk me through useEffect, including the dependency array and cleanup function. What are common mistakes people make?
When does useMemo or useCallback actually improve performance, and when does it make things worse?
What is useRef used for beyond just DOM references?
How does useContext work and what are its limitations for state management?
How do you build a custom hook, and what makes something worth extracting into one?
What are the rules of hooks and why do they exist?
Given a component that's re-rendering more than expected, how would you debug it?

“Felt fine on this one.”

Boeing full-stack interview that leaned harder into TypeScript internals than I expected. The question felt academic at first but they really wanted to see if you'd actually used this stuff in production, not just read about it.

What is the difference between nominal and structural typing, and which approach does TypeScript take by default? Walk through a concrete example where two types are structurally identical but represent different concepts, and show how you would enforce nominal-style type safety in TypeScript.

“I knew TypeScript was structural, so I started there.”

Boeing full-stack interview, one coding round that was pretty much a classic string problem. Nothing surprising about the format but the follow-up pushed a bit harder than I expected.

Given a string, find the length of the longest substring that contains no repeating characters. Then discuss how you'd optimize it further.

“Got the sliding window approach down fine, used a hash set to track what's in the current window and moved the left pointer when I hit a duplicate.”
