In the HR prescreen call for the Meta Front End Engineer position applied for in the spring, it was noted that the questions were quite standardized. Unlike previous Meta interviews, which did not typically include such standardized questions, this one might be different due to the specific nature of the front end position.
-
The call lasted for 30 minutes.
-
The first twenty minutes mainly focused on discussing previous work experience and projects, although the conversation was abruptly interrupted due to being too talkative.
-
The last approximately ten minutes covered standard JavaScript questions, as follows:
- Difference between apply and call
- Explanation of ‘this’
- Var versus const differences
- Familiarity with the DOM, including how it is structured in terms of data on a webpage
- Explanation of event delegation
- Implementation of event listeners
- How to determine the depth of leaf nodes in a DOM tree
It was mentioned that it was unexpected to encounter such standardized questions in job interviews in the United States. The individual felt a bit challenged by the final question, unsure if there is a JavaScript API specifically for finding the depth of leaf nodes. They mentioned using depth-first search to keep track of levels as a response and requested assistance from anyone who knows the answer.
