Share a job by a candidate should be done using Talemetry email system
When a candidate wants to share a job from a Career site, it launches the user's default email system. This is cumbersome and difficult because the URLs to apply for the job, or any text in the email can't be controlled.
The email should be sent via the Talemetry email system. A captcha or other control to ensure that bots are not using the system and it is a human should be put in place
