1st round, react related, hooks, testing your knowledge of rendering and how to write custom hooks. So polish up on that. Know your react.useMemos, and what callbacks are for. Understand why re-rendering loops might occur.

During the technical interview, the panel asked thoughtful and insightful questions about my approach to the project. Some key questions included: TrackBy in Angular: They asked if I had considered using the trackBy function in the *ngFor directive to optimize rendering, especially for lists with frequent changes. SwitchMap in NgRx Effects: They wanted to know why I chose switchMap for handling asynchronous operations in my effects instead of other operators like mergeMap or concatMap. Modules vs. Standalone Components: They questioned my decision to use Angular modules instead of the newer standalone component feature, exploring my thought process behind that choice. Staying Updated as a Developer: They asked how I ensure that I stay up-to-date with the latest developments in Angular and the broader tech ecosystem.
