The 30 second answer
The reported loop has five rounds, and none of them is classic algorithms. There's a multi-part string-parsing screen, an integration round where you extend an existing codebase with HTTP calls and response parsing, a bug squash round in unfamiliar code, an AI-assisted coding round, and finally an experience and goals deep dive. So I'd practise parsing, HTTP and JSON, debugging, testing and clearly explaining my trade-offs.

The 30 second answer
First I make sure the project builds and the tests run before the call. Then I reproduce the bug and restate expected versus actual behaviour. I follow the code path from the entry point to where the value first goes wrong, using breakpoints or logging, and test one hypothesis at a time out loud. I make the smallest fix for the root cause, rerun the tests, and add a regression test.
2.2 How should you work in an interview round where AI coding tools are allowed? Medium I treat the AI as a fast pair, not the author. Before each prompt I say what I'm asking for and what I expect back, then I read the generat…
The 30 second answer
I treat the AI as a fast pair, not the author. Before each prompt I say what I'm asking for and what I expect back, then I read the generated code line by line and check it against the requirements. I write and run tests for every part, and when the output is wrong I explain why and fix it. The interviewer is watching my judgement, not my typing speed.
