JavaScript Interview Questions

Interviews for IT jobs including JavaScript jobs often include challenges far beyond the usual questions regarding career aspirations. IT job interviews often consist of brainteasers, riddles and practical questions designed to measure your logic, reasoning, creative thinking, and problem-solving skills. The objective for the interviewer is not only to assess your technical knowledge, but also your communication skills and suitability (culturally) for the company.

Here are some example JavaScript job interview questions to help you to prepare yourself (answers can be found at the bottom of the page):

Tags/Keywords

Our innovative and custom-written search engine places an importance upon tags chosen to be representative of the content, however it also indexes all content to provide you with the most relevant results

Please note that the Quick Search operates as Boolean search, so you can narrow your search by including operators such as "and" if more than one term is required to feature in the results. "+" will also work in the same way. I.e. "php and mysql london" is the same as "+php +mysql london".

The operator "or" does not need to be included as this is the default, i.e. "php or mysql or london" is the same as "php mysql london". You can also use "not" or - to exclude terms.
