Trainee Broker Interview

Hey guys, hope you all doing well. I got an interview for trainee broker position and I've never been in it before. I am concerning about what kinds of questions they would probably ask? will there be many technical ques? like any financial instrument pricing method?

In addition, what kind of work experience would be best fit for a broker position? could you please give me some examples? like successful sales experience...

And one more, if they ask: tell me something interesting in the market?
which kind of information about the market should I focus on to ask this ques? like index, rate adjustment, oil price and forex sth etc?

I got the interview in two days, so it would be very appreicated if you guys could give me a hand here asap. Thanks in advance.

All the best,
Kenneth

They will ask the following riddle;
'What = 37 cents with two coins?'
Me and the guy who interviewed laugh now on how long i took to answer that; He said an extra 10 seconds and i'd been out the door! Its a very standard question i believe.

3700cents?
