Both me and Ms.Sparrow are busy people and we read every application we receive and talk about it first. I tend to get less applications sent to me for some reason despite the instructions stating to send it to both of us. That in itself creates a delay.
It could take up to a week for your application to be reviewed, but it will be reviewed. If we like the application, then the process will be immediate. We have to think about our group dynamic, what we can offer, and what you can offer us.
