Guys,

Does anybody know a website containing questions in C++ from interviews? May
be there is some news group where people discuss questions they got on the
job interviews.
I know that many employers trust in the BarainBench tests. Is there a
website where there is a list of questions similar to those on the
BranchBench site?

Thanks a lot

It's not exactly about job interviews, but
http://www.gotw.ca/gotw/index.htm has quite a lot of question/answer
pairs that cover large areas of C++. If you like them, you could also
take a look at Herb Sutter's books (same website), they are written in a
very similar style but more comprehensive.

A lot depends on the level of person your looking for. When I was
vetting for C++ programmers with OO experience, I usually started out
with "When and why would you declare the destructor virtual?". That's
usually sufficient to eliminate 90%Sad. (And I wasn't looking for a
complex or detailed answer -- I'd accept just about anything which
contained the words delete and derive.)

Given that, I suspect that most of the questions at Herb's site are a
bit too difficult.

Google brings up: http://www.techinterviews.com/index.php?p=110 .
But the scope of these questions is limited, and some are really
about OOD (nowadays not what makes C++ unique).

Someone mentioned gotw for advanced questions.
A better option might be to pick the table of content of one
of Scott Meyer's C++ books, and derive a question from any item.
You can even plainly give the item title and ask the candidate
to guess what it would be about.

I do not know of a site with equivalent questions.
While such a test can be used to save time when screening candidates,
these would not be good *interview* questions IMHO.
Questions in a personal interview should be more "open": they
should help reveal the candidate, not corner him with a technical
quiz. I usually *end* an interview with targeted technical
questions, only to validate the level of proficiency that the
candidate claims / was assumed to have.

Ivan

I don't think this site is reliable. It serves things like:

Quote:
10. What is an incomplete type?

Incomplete types refers to pointers in which there is
non availability of the implementation of the
referenced location or it points to some location
whose value is not available for modification.
(...)
Incomplete types are otherwise called uninitialized
pointers.

class foo;

class bar {
foo& m_f;
......
};


In the above, foo is an incomplete type. There is just enough information
for bar's interface to compile without foo being further specified.
Presumably, the rest of foo's definition will be available when bar is
implemented.

Yes, and I bet most people in this newsgroup know it.
Similarily we distinguish between types (which can be
incomplete) and variables (which can be uninitialized).
Likewise we know that pointer type is always complete, etc.
This is the editor at www.techinterviews.com who does not.

Yes. And in this:

class foo;
void proc( foo x );

foo is also an incomplete type, but there are no pointers involved.
Incomplete types have little to do with pointers.
