When hiring a Web Developer, look for a candidate with an extensive portfolio of previous development work.

Each of those scenarios demands a different level of expertise to successfully carry out duties on a daily basis. For example, a candidate who will be joining your existing web development staff should show a history of being a good team player and perhaps bring greater technical expertise in a specific area; a candidate being called upon to lead will have to display leadership qualities combined with a superior command of technical knowledge across the board; and a solo operator will have to bring a broad knowledge base and skill set, and be creative enough to acquire needed additional information from outside resources.

However, be sure to add inquiries specific to the role they’re interviewing for, so you can gain valuable insights into their likelihood of success in that position.
