The performance of the video interview could be greatly effected by the distance to your servers. Do you have servers in the US and other countries to conduct the interviews?
I'd like the time to prepare to be zero. I want to see the reaction of the candidate to the question. Can this be done?
Is there a time or number of questions limit for each interview? do you allow more than just video answers? Can multiple choice, true false, type questions be asked?
Ability to download all videos from a specific respondent in one click.
Ability to customise or completely Whitelabel the showcase link. Eg. app.willotalent.com/show/xxxxx becomes mycustomdomain.com/show/xxxxx
