Perguntas de entrevista de vagas de JavaScript Engineer Co-op da empresa Global Relay

This is a in-person interview with 2 from tech group and 1 HR. They first asked me some simple math problem then the HR asked me what I know about their company. Next came the tech question about how the website works and some details about HTTP and PHP. Also I was asked about how do I like web applications. I apply for the job through my school's co-op office but unfortunately I didn't get this job.
