Had my interview yesterday and got the job!
Here's a quick summary for anyone going in-

Started with their presentation and Q/As from us. Then a 35 question written test covering some weather, IFR regs, questions on an airport diagram(T/O mins) and ILS approach, and some PSA questions. A couple questions on "What would you do" scenarios.
Then a combined HR and tech interview. A couple of standard HR questions and then Tech was basically a whole flight from CLT to IAD with some weather reports. Asked if we can take off with this weather, departure alternate, SID/STAR charts and then brief the ILS, questions on that approach. Then asked me a question on what I would do if something went wrong in flight, basically looking to see if you think about all the resources available to you to find a solution.
Just be a nice guy/gal, know your Jepps and weather and you shouldn't have any problem!

Send me a pm if you have any more questions.

Good luck and see you guys soon!
