Yes there is a form that Virgin Blue pilots can fill out if they wish to recommend a pilot, it makes it easy for the person in charge of recruitment. They can attach the form to the pilots application, and it makes it easier to refer to when an if needed. They have been in use for almost a year now. I don' think it matters how many forms are put in. But from what I hear most pilots who are getting interviews have had at least 2 recommendation forms put in for them, but I do know 2 pilots who only had 1.
I believe those with FEB dates have been notified, not to sure about March.
