- This is one of the questions I have used, and suggested here. The point
- here is not that I want someone to do this when working. I want to find
- out what they know specifically about the C language. When we look for
- applicants, one of the skills listed is a level of proficiency in C.
- All the resumes we get indicate some level of expertise in the language.
- I use this, and the question about reversing strings to assess that
- knowledge. (If someone writes on their resume' that they have spent the
- last n years writing C and can't write a simple function to sort some
- integers in the limited time allocated to an interview, I am going to
- have definite reservations about the individual (both his C knowledge
- and his honesty.) If you gave me the above answer, I would heartily
- agree and still ask for some notes. (As an aside, I would 'grade' you
- higher, you also show that you know and would espouse a more elegent
- solution than the one being foisted on you.)
-
- My point is that this group has been asking for a (hopefully) small set
- of interview questions. Another comment made which I respect is the
- comment about what to do when interviewing someone who says they have
- no C knowledge, but are confident of their ability to learn. I would
- find that a valid answer, and depending on the other applicable knowledge,
- would not bias me against that individual. These quizzes are for
- weeding out those individuals who are trying to B.S. their way to a
- job. I will quiz someone on every bit of knowledge that is claimed on
- a resume. I have UNIX shell programming questions, regular expression
- quizes, C++ quizes, MS windows ... . . If an applicant claims a set of
- knowledge, I take that as a right to assess it.
-
- The bulk of time when I am interviewing someone is to pose one of the
- design problems we are working on, or have recently concluded and ask
- the interviewee how he/she would solve it. We have a whiteboard, and
- markers and have a very lively and useful discussion. That is what I
- use as the biggest single factor. I get to find out how someone thinks
- on their feet, and how they will apply what knowledge they have.
