Forio Web Applications Developer interview questions

I applied to this job on our university's career board. A few days later, their HR called and asked some general questions about my resume. She specifically asked about my experience with JavaScript. A few days later I got a technical phone interview. The interviewer was one of their senior web developers, who was really nice. We used an online coding board (I forgot the name) for the interview. At first I was asked to write some basic CSS (for example to let a div align horizontally on the page). Then I was asked to solve an algorithm question in JavaScript.
