Angular and Vue developer interview questions: 23 to prepare for

1. Walk me through a recent project where you used Agile. What did you do yourself?

   58% of today’s 57 open Angular and Vue developer postings name Agile.

   A good answer shows: Your own hands-on part, the choices you made and a number for the result.

   Sample answer: “In my last role I rebuilt the order service in Python, cutting median response time from 480 ms to 190 ms at the same traffic. I did that part myself: I chose how to do it, checked the result and explained it to the team.” Then say what you would do differently.

2. What is a mistake people often make with SQL, and how do you avoid it?

   21% of today’s 57 open Angular and Vue developer postings name SQL.

   A good answer shows: That you have used it long enough to know where it goes wrong.

   Sample answer: “In my last role I rebuilt the order service in Python, cutting median response time from 480 ms to 190 ms at the same traffic. I did that part myself: I chose how to do it, checked the result and explained it to the team.” Then say what you would do differently.

3. How would you explain Jira to someone who has never used it?

   7% of today’s 57 open Angular and Vue developer postings name Jira.

   A good answer shows: That you understand it well enough to make it simple.

   Sample answer: “In my last role I rebuilt the order service in Python, cutting median response time from 480 ms to 190 ms at the same traffic. I did that part myself: I chose how to do it, checked the result and explained it to the team.” Then say what you would do differently.

1. What is the difference between const and let?

   A JavaScript question (63% of today’s postings name JavaScript). More in the JavaScript skill test.

   Answer: const cannot be assigned a new value after it is set, let can. Use const by default and let when the variable must change. Avoid the older var.

2. What does typeof null return?

   A JavaScript question (63% of today’s postings name JavaScript). More in the JavaScript skill test.

   Answer: "object". This is a well-known quirk from the early days of the language. Check for null with === null.

3. What is the difference between == and ===?

   A JavaScript question (63% of today’s postings name JavaScript). More in the JavaScript skill test.

   Answer: == also converts types before comparing, === does not. 5 == "5" is true, but 5 === "5" is false. Most teams use ===.

4. What does [1, 2, 3].map(n => n * 2) return?

   A JavaScript question (63% of today’s postings name JavaScript). More in the JavaScript skill test.

   Answer: [2, 4, 6]. map returns a new array with the function applied to every item.

5. What is a React component?

   A React question (37% of today’s postings name React). More in the React skill test.

   Answer: A function that returns a description of one part of the screen. A component is a function that takes inputs and returns what should appear on the screen. A page is built by placing components inside other components.

6. What is JSX?

   A React question (37% of today’s postings name React). More in the React skill test.

   Answer: A way to write markup inside JavaScript; a build step turns it into ordinary function calls. JSX looks like HTML but lives in JavaScript files. Browsers do not understand it, so a build tool converts each tag into a plain function call first.

7. How does a parent component pass data to a child?

   A React question (37% of today’s postings name React). More in the React skill test.

   Answer: Through props, written like attributes: <Price amount={20} />. Props are the inputs of a component. The parent writes them where it uses the child, and the child reads them as one object.

8. Can a child component change the props it receives?

   A React question (37% of today’s postings name React). More in the React skill test.

   Answer: No: props are read-only, so the child asks the parent to change them, usually through a function passed as a prop. Data flows down from parent to child. To send a change upward, the parent passes down a function such as onSave, and the child calls it.
