Back in 2017, I interviewed at Barclays for an Angular position. The process included a written test and a face-to-face interview. I scored 22 out of 25 in the written round but didn’t clear the F2F interview.

When I mentioned that I had performed very well in the written test, the interviewer responded, “Haven’t you ever screwed up?”
It was only later that I realized the gap — RxJS was the missing piece. In your case it could be Signals.

Since then, I have taken hundreds of interviews and also appeared in many myself. With over 10+ years of experience working with Angular since its inception, I understand what interviewers look for and the specific order in which they expect concepts to be presented.
In this semi-book cum blog, I share a clear recipe to crack any Angular interview by breaking down the interviewer’s psyche.

Below it the essential list to crack the interview.

*  RxJS 
*  Change Detection
*  Dependency Injection
*  Design Patterns
*  Performance
*  Signals & It's related topics.
*  Testing
*  Other miscellaneous topics

So lets get started

Hi Pawan ! Could you please brief me about yourself?
