Senior Front End Developer Interview Questions
1,429 senior front end developer interview questions shared by candidates
On my laptop i was asked to create a complete site from a picture and a few assets in under an hour. (complete HTML5, CSS3, JavaScript, Animation, Image Sprites.. etc etc etc)
They asked me to re-architect my answer to the JavaScript code I had submitted for the online questionnaire. The code requested in the online test was required to give a very flexible approach to rendering charts. It had already taken me more than 5 hours to do this from scratch, so I found it impossible to do this a second time in a different way. As I mention above they wanted a very specific answer to this, which is roughly what Java did when they built the AWT and Swing.
