1,605 angular developer interview questions shared by candidates

Questions in technical interview was related to the coding assignment that you have to submit. Most of the questions were from the practical part rather then going into the theory, that was a plus point. Some of the questions that I remember are as follows: 1. Difference between ViewChild and ViewChildren? 2. What are the Guards? 3. How you handle unhandled errors or exceptions? 4. What are interceptors? Some general HR questions about your work and responsibilities in current job, reason for the job change etc.

1. What is a closure? 2. In a garbage-collected language like JavaScript, how are memory leaks possible? Describe the low-level mechanics of a memory leak. 3. What would be the challenges in implementing a dead code elimination tool that targets JavaScript, as opposed to one that targets a language like C# or Java? 4. JavaScript performance has improved significantly over the past 10, 5 years, and is continuing to do so. What are some of the implementation techniques that have enabled this? 5. New JavaScript language features have been added over the past 10, 5 years, too. Is it possible that new language features can actually improve the performance of applications? Or, would you expect new language features, in general, to have either zero or negative effect on performance? Why or why not?
