Just found the email from Delta:

Dear Forgot to Bid,

The Delta Pilot Selection Team invites you to visit our Employment Office in Atlanta to be considered for the position of pilot. This process may require two consecutive days of your time. On the first day you will be tested and interviewed. If you receive a conditional job offer after the first day, on the second day you will undergo a company medical examination and take a psychological test with a follow-up interview by a psychologist. If you are interested in participating in this process, you should contact the Delta Air Lines Chief Pilot...

^^^ is that what the invites still look like? ^^^
