What C/C++ concepts a programmer wishing to enter embedded systems programming(for RTOS using C/C++) and going for an interview must know ?
I have heard of the following
1).Function pointers
2).static keyword
3).memory management using malloc and free
4).bit manipulation

Can anybody else add more topics to the list?
 

1. Virtual Functions
2. Macros
3. Threading
4. Software Timers concept
5. Stack concept

a.) The volatile keyword is fundamental in embedded systems
b.) What are the stack and the heap and what are these used for
c.) Multitasking and task synchronization mechanisms
d.) Advantages of multitasking
e.) MACROS
 

Interrupts (Outside the scope of ANSI C but pretty fundamental to a lot of embedded code).....

Really, you need to know C plus a reasonable amount of computer architecture and the common ways the 'implementation defined' bits of the C standard map onto the hardware.
Some understanding of linkers is helpful, as you will surely end up needing to write custom linker scripts.

Have a look at the MISRA standards for automotive C, last time I looked at them they did not all make sense, but they did provide a rough guide as to what you should think twice about doing in an embedded context.

Regards, Dan.
