Interview tips and tricks.
Know who you're dealing with.
Who's the boss, who's the chief pilot etc. (very important when out on the lash, if you see either of them, run!)
Know that company's niche/specialty.
Know their main area of operation, ie the bread and butter.
Know their fleet and who the main competitor is and why company X is "better". (naturally, reverse when being interviewed by company Y)
Why do you want to work for X?
What skills can you bring?
How can you make a scenic special? (assuming they do scenics etc)
How will you deal with X type of passenger?
Essentially, the boss wants to see if you are interested enough in his company and can you fit in with it.
Have a good idea about the a/c you fly now. Know the battery size, fuel load, pay load etc. Basic stuff a pilot ought to know.
Check ride can be any thing from a couple of circuits to a session out in the training area to SID-cruise/gen handling-STAR-ILS. It depends on the job of course.
