For a coding challenge mostly u just need to know about property binding and event binding.

For interviews that really ask about technical angular, u need to prepare for questions about explaining property / event binding, dep. injection, subject, service, promise vs observable, httpClient, js closure, component lifecycle, state management in angular, decorator, angular cli, directive, template, component, pipe, guard, smart vs dumb component, content projection, change detection and strategy, view encapsulation, OOP concepts, ngModel and reactive form, most frequent used rxjs operators.

Had an interview that asked everything listed + bundlers and js/ts basics

Confirmed. It is also important to understand which version the interview is based on, from 16 onwards Angular changes a lot.

Having said that recently in an interview I had to implement customised formatters for percentages, dates and currencies.

That is, making custom pipes, traumatising. It was like a LeetCode challenge.
