Only been here for a couple of months, but.....

1. Our captains don't show up drunk (or at least not the ones i've flown with).

2. We do get cleared for approaches 80 miles out at FL240, nobody flies to mexico more than we do. The way to handle it is different for different approaches. Make sure you stay above mea, the rest is common sense.

3. The same applies to pretty much all your questions. I've found all the CA's ive flown with to be extremely professional, and for the most part are mindful of the FAR's and apply common sense to situations. All the preflight questions, smoke in cabin questions, bad weather issues, and weight and balance issues you addressed would be handled swiftly, professionally and in what ever manner is deemed appropriate in the interest of safety.

Most of those questions that you've found on aviationinterviews.com are generic questions designed to ascertain what sort of person you are, how sure you are of yourself and where your head's at.
