We are seeking a Frontend Engineer who can expand our product portfolio and make life easier for locals and local businesses. As part of this role, you will build experiences that help users engage and feel comfortable with the products and services we offer.

We need you to understand the philosophy of writing clean and modular code.
We need you to take your own stand and do what's right to find a solution.
"I'd rather listen to a possible solution rather than a 'don\'t know'" would be plausible to you.

Technologies mentioned above is what you can relate to while applying but that's just the tip of the iceberg.

If you get a score of 10 below,
We need you

You need at least 5 points to proceed to next round.

Answer the following questions by attaching a document link with the note:

1. Why choose ngRx over shared angular services? 1 point

2. How are fork join and merge map different? 1 point

3. How do we wrap html elements in our custom component? 2 points
   Ex:

This is not a paragraph element

1. How will you handle an error produced by RxJS operator's inner observables without failing any other observables that are yet to emit values to its subscriber, so that all the inner observables including errored ones can be piped to another RxJS operator such as fork join, concatMap etc to be handled smoothly for further operations?

Easiest thing would be to generate a pseudo code.

With above question solve this problem:

[Observables....] -> Emit values simultaneously from the array of observables at once (perform a task when an observable finishes) -> toArray -> [emitted values...] -> process each emitted value one by one -> toArray

This will give you 4 points

1. How does javascript achieve its asynchronous nature being single threaded? 2 points
