@nkumar-topcoder we would need your help to fix it in Sendgrid:

1. Update templates in Sendgrid as we updated them inside source code:

• https://github.com/topcoder-platform/taas-apis/blob/dev/data/notification-email-templates/taas.notification.interview-expired-guest.html
• https://github.com/topcoder-platform/taas-apis/blob/dev/data/notification-email-templates/taas.notification.interview-expired-host.html
• https://github.com/topcoder-platform/taas-apis/blob/dev/data/notification-email-templates/taas.notification.interview-invitation.html
• https://github.com/topcoder-platform/taas-apis/blob/dev/data/notification-email-templates/taas.notification.interview-schedule-reminder.html

2. Inside Sendgrid set subject to {{subject}} so it's not empty
