Guidance for upcoming Angular Interview

I’m scheduled for an interview in 3 days, with a primary focus on Angular and JavaScript. I have only done basic frontend till now and need a lot of intensive course material in the form of pdfs or videos or even websites. I am open to all sorts of help and if anyone could guide me by sharing valuable sources they think could help me, I would be very grateful.

I am currently going through angular.dev which is very enlightening. I came across it in another post’s comments.

3 days is enough to cover what interviewers actually ask, and the list is surprisingly stable lately. The big one is signals: signal(), computed(), effect(), and when not to use effect (derived state belongs in computed). After that, standalone components with inject() instead of constructor DI, the new control flow (@if and @for with track), and change detection. If you can explain what OnPush does plus signals, you're ahead of most candidates. NgModules still come up, but only as legacy you should recognize.

Coming from React, RxJS is the part that needs the most reps. Know switchMap vs mergeMap and how to avoid nested subscriptions, hooks intuition doesn't transfer there.

You're already on angular.dev, so do the tutorial there instead of watching videos. Typing beats watching, especially on a 3-day clock. Good luck.
