In the detailed review of my code I spoke a lot about how I balanced using React and Next.js best practices against less conventional and even old-fashioned low level coding techniques. I was asked how I might balance my "old school" ways of doing some things against the "new school" ways done by the dev team.
Implement a function `Car` that will result in the following output: var a = new Car(); var b = new Car(); console.log(a.id); // logs 1 console.log(b.id); // logs 2 b.id = 3; console.log(a.id); // still logs 1

First round : A problem with page structure was given. It was kind of a recursive problem and the idea was to show it the same way on the front end (Eg directory structure). The expectation here is to tell the interviewer your approach, ask clarifying questions before hand and keep the interviewer engaged in conversation. Try to list down error-handling scenarios. If you follow TDD you might get bonus point here. Round 2 : I was asked to implement a production-level feature toggle utility kind of function. I tried to did it in TDD way to some extent and show a working solution in react. Unfortunately, I clear this round. I am not clear on what was the expectation here, was it more of a library function like a package and not a solution demonstrated in a working project?
