Qt job interview questions

Hi!
Some days later I will take a job interview for some Qt developer vacancy.
I need a list of possible Qt-related questions to prepare myself.
Some time google searching didn't give me any results.
Your help will be very appreciated.
Thanks in advance.

Sorry to say please don't take interview, if you are not able to decide which all question you should ask in interview, better you don't take interview.
If you have worked with Qt, if you have good experience in working with Qt i guess its very easy to get list of question by ownself only.. so better try to get ur own questions or don't take interview.

sorry to be rude.

These question are more with theoretical and Qt architecture level not for programming level.



1) How qt differs from other mobile development platforms like android?



2) If worked with GTK what is the difference between QT and GTK?



3) What are the striking futures of QT?



4) What is Qpointer?



5) What is dpointer?



6) What is MVC architecture? How it is organized?



7) What is a signal? And how will it differ from event?



8) What is a slot? And how it differs with callback Method?



9) What is the difference between signal and slot mechanism and Callback mechanism of GTK?



10) How many signals at maximum you can connect to a single slot? If more than one how you can do that?



11) How many slots can you connect to a signal? If more than one how those slots will be executed?

(The order of execution)



12) What is QCast and how will it differ compared to c++’s dynamic cast?



13) What is the use of Q_OBJECT macro?



14) What is MOC and UIC? Explain how they will work for compilation in QT?



15) What is qmake? (Explain the usage of it)



16) How a QT Program/Application written for one platform (Symbian) can be ported/executed in another

platform (Maemo)? (Explain If you need to make any changes or you need to recompile)



17) What are all the platforms/OS currently QT supports?
