Panel interview. Done only once. So that is good to get it all out of the way. Long process to hear back from, after the interview. The interview it self was easy, what you would expect, just the wait time to hear back.

1 phone screening + 1 panel + 1 additional on-site interview. The whole process takes more than 3 months, so be patient with the long process. Don't have other advice about the process, because it's easy questions.
