Candydate’s targets are not on the technical or professional side, but the hospitality and retail industries. Restaurants, cafes, hotels and stores in general. Basically those with high turnover rates and continuous hiring needs, where training is provided.
The idea is candidates won't waste time with long applications and employers can flip thru video-pitches instead of reading template CV's, saving everyone's time.
For introverts (odd for customer facing roles) they can just submit the old CV and skip the video, or by point the camera to a wall while they talk ; )
