In terms of Qt, probably start with the following as it underpins a lot of Qt development:

Signals and Slots[^]
Object Ownership and Lifetime[^]
Events[^]

However, Qt is huge and even the above may be too much to cover in 1 week. Depending on how they use Qt, there may be questions on networking and QML[^], as well as specific questions on classes. I've found it always pays to be honest in interviews and say when there is a gap in your knowledge, rather than answer a question you don't know the answer to.

Good luck!

Thank you jsolution_uk. I don't have much experience in QT. Your given documents are very useful for me. Please let me know if I need to do anything other than given link. Do you have any good example for QT networking. I would like to study that code. It will give me a brief idea how netowrking works in QT.

You know a week is avery short time. I hardly believe you can properly prepare yourself for the interview. However:
C++ has a new standard. If you have already a good knowledge of the language I suggest you to learn just a few highlights, this article, in my opinion, is good for: Ten C++11 Features Every C++ Developer Should Use[^]. On the other hand if you don't know C++, you better try to understand the basics of the language.

I don't know QT so I can't suggest you anything on this argument.

If you already know SQL, then I suppose a quick refresh of your knowledge would suffice.
On the other hand, if you haven't a working experience with, it is time of studying an make a bit of practice.

1)OOP concepts-encapsulation,data abstraction,inheritance,polymorphism
2)Data Types, Variables-const,static,readonly
3)access specifier-private,protected,public
4)Abstract class
5)interface
6)collection - hast table,map, vector, binary tree
7)Multi threading
8)Memory Management
9)Pointers-void,far,near,wild
10)virtual functions
11)Marshaling
12) SDI,MDI
13)TCP/IP client server connection
14) Message passing, delegation, IPC

If you know half of the above THOROUGHLY you will do pretty good. :-) Don't worry so much about which topics you might have forgotten.
