How to interview a frontend developer?

The KISS Principle for interviewing a frontend developer.

Ask him the following questions:

  1. What is HTML?
  2. What is CSS?
  3. What is Javascript?
  4. What is frontend development? (Optional for interns and juniors, must for mid to senior developers)

Let him speak for at least 10 minutes on each of these. What he tells you about these technologies will help you understand the depth of his understanding. For the same above questions, the answer of a junior developer will vary significantly from a senior developer. You can cross-question him on any of his statements if you think he has memorized the answers for the above.

After the above questions are answered, you can ask (if required) that which is more relevant to your product/company.
