An excerpt from a feedback of an interview

Himadri seems to be somewhat familiar with pointers in C. As you know, I use this as my yardstick to gauge the candidate. Her rating:
3 out of 10 in C
5 out of 10 in general software development

(10 is denotes the proficiency of an international standard software developer)

By the way I would like to give Madhusudan one more point in C++. His rating would be 2 out of 10.

It's not possible to compare proficiency in C and that in C++. Although C++ is a superset of C, when we interview a candidate for C++ we look at OOP skills in C++. This is not tested when interviewing a candidate for C.

Moreover, C skills are usually preferred when the requirement is for embedded platforms. And C++ skills (OOP) is usually preferred for developing enterprise software.
