First Interview Invitation!

I could hardly believe it when my phone started buzzing and ringing today. I looked to Drew's email and it said that he had an email from ERAS. My hands were shaking as I went to check the email and try to reply and accept the invitation!
Although we were hoping for an interview from this program (because Drew is doing a sub-I there next month) we were not expecting an invitation already. I replied to the program coordinator and asked if it would be possible to interview during his sub-Internship - and if not his first choice would be to interview in November. I got a prompt response letting me know that he could interview in October while he was there. Although Drew has housing while he is there they still offered to book him a hotel - this program is one of the few that actually arranges and pays for your hotel accommodations!
I should also explain that I have Drew's school email forwarded to my phone so that I can respond to any interview invitations. This is because with his sub-Is this month and next month he will most likely be in surgery when the invitations come in via email. Some programs send out (for example) 15 invites when they really only have 10 time slots. This means that only the first ten to respond will actually get the interview.
Luckily neurosurgery is one of the more organized programs and 95% of the programs have actually posted their interview dates (this is not the case with all specialties). With this information I used Google Calendar to enter all of the potential interview dates... then we will use the calendar to try and schedule the interviews as they come in. Right now many of the interviews conflict with each other but I imagine things will manage to work out as we would be lucky to be invited to half the programs we applied to; therefore I imagine by process of elimination it will be pretty easy to schedule interviews.
I hope this is just the first of many more interview invitations... but we'll just have to wait and see!
