UI Developer - Interview Questions
If my website was slow, how would you diagnose the problem and fix it?
I would inspect various factors on your website. One thing I would do is use a link analysis tool to see if there are any dead links on the website. I would also check the coding on various pages of the site. One solution to the latter problem is to link similar pages to one CSS sheet and simplify the coding.
Another thing I might do is move the JavaScript coding near the bottom of a page’s HTML document. This allows the page to show before all JavaScript coding is downloaded. Additionally, I would check the servers of the website. If allowed, I would change the distribution of the website to a content delivery network. This allows users to access the website via a server that is closer to their locations. After all this, I will again test the speeds of the website.
