We use this for both live video calls and one-sided video interviews. For live video calls its really nice since the people that we are inviting to the video calls do not need to install any software or sign up for an account. They just get an email with the date and time and a link where they can join. It works right out of the browser. We also use this for one-sided video interviews and tests. It's really easy to set up a 10-15 minute interview with questions that the user has to record a video answer to and then we get the videos they record to review.
Its helped us in multiple ways. Video calls let us get around problems we had with trying to get the candidates to come in person for a chat if they lived out of state. Having one-sided video interviews let us screen candidates better. Its easier to find a more suited candidate if you can watch a video of them and then move them forward with the process rather than relying on just a resume or a phone call.
