Intuit Staff Systems Engineer interview questions

There was a manager interview, and a tech screen with two other members who were on the team. They were at the start of a migration project moving from o365 to Google Apps. They were heavily focused on email routing issues, and how to maintain deliverability during the migration. There were some questions about Google Calendar, and Google drive. I felt like the interview was too focused on email delivery, vs other problems that would arise for Google Drive/Calendar post migration. After the tech screen I never heard back. The recruiter who I had spoken to many times, to coordinate interviews went radio silent, and never bothered to return my emails or calls.
