The fact of being web based helps a lot, so that the candidates don't need to install any software nor the interviewer. The code highlighting for code interview and the graphical tool for system design interviews are also very good. There is no delay on the interactions. Review collected by and hosted on G2.com.

I believe that they haven't yet found the sweet spot for testing interface during the code interview, a better way so that candidates can create tests for their code should be on the horizon. Review collected by and hosted on G2.com.
