Why (and when) you need killer HTML skills

Looking for a Web Developer, Front-End Developer or UI Engineer? Then you’re gonna need a candidate with A++ HTML skills. 

Since HTML is technical stuff, you need proof your candidate knows what they’re talking about. Here’s how you test it:

  • Ask candidates to complete an assignment using HTML.
  • Ask candidates targeted HTML interview questions.
  • During interviews, ask them to comment on existing HTML code or explain their HTML assignment via a presentation.
  • For junior roles, ask basic questions to see if they get HTML, CSS and/or JavaScript.
