Quick update from the post above,
Kept browsing after I changed my appt and I found another cancellation, this time for July 20 (4 days from now) so I snagged that one.
So moved from October 9th to August 7th to July 20th all in a matter of a few hours
Keep checking if you're not happy with your interview date, there definitely will be cancellations.
Cheers,
