What does each job application status mean?

In the Applications area, applications can have four different statuses. These include: 

• Accepted - The company has accepted the application and wants to continue with the screening process. 
• Not Accepted - The company has decided not to include you in the screening process. 
• Pending - The company has not made a decision. When a company doesn't take action on a job application, it expires after two weeks.
• Status Updates Offsite - The company uses an Applicant Tracking System integration and manages applicants outside Wellfound:
  If interested, they will contact you through conversations or email to start the screening process. These applications will not receive the same status updates as other applications.
