The Captain Review Board for the cadet program is just a quick check to make sure nothing has changed since the time that you met with them and now. It could have been 2-3 years ago, and a lot could have changed since then. You could have a few felonies now, for instance. They also want to take a quick look at your logbooks to make sure that you meet ATP minimums. It is amazing how many will show up at an interview and not have the required cross country or instrument time.

If they ask you technical questions, it is likely just so that you know what they expect your knowledge level to be when you show up to class. They may talk about approach plates and things, and that will either show you that you are already very knowledgable and ready for class, or that you have some studying to do before ground school.

It isn't a true interview, just a meeting to go over everything. It is also a time where you can ask questions and get more information.

Choosing a regional over the type of the airplane that they fly certainly shows some immaturity in the industry. Base it on domicile and quality of life first, then about 100 other factors, and airplane last. The CRJ and 175 are both comfortable and really are not very different. Both are modern jet aircraft, well maintained, and very easy to learn. If you live in an Envoy base, and you can hold it in the near future, go there.
