No, just fix it…

Why do business feel the need to explain to me the inner workings of their business process?  I do not care, and I do not know why you think that I would care.  I do not work at your company, and I do not do your job.  Your are providing my a service, and the only thing that I am concerned with is you rendering the service.  If you cannot provide said service apologize, tell me how you are going to fix it, and then fix it.  Please do not explain how Sue told Bob XYZ, when she should have said ZYX.


I really enjoy reading about the various interview questions used by people in the industry when interviewing new candidates.  Go check out the big boys, and you will see what I mean.  There are literally web pages, and blogs dedicated to interview questions.  Heck, there are legions of pages dedicated to Google’s interview questions.  What I want to know is where I can find those people.  I am never even approached asking those questions in an interview.  I must be, or have been working for the wrong company.  Perhaps Google can attract that talent, but my employer cannot.

The programming question that I ask is usually very easy to answer.  At least, I think it is.  There are multiple solutions to the problem, and I always preface the questions by saying, “You can answer it any language you want.”

You are given a string of floating point numbers that are delimited by a pipe character.  How would you parse the string into an array of floats.  You do not have to worry about memory management, and you can solve the problem in any language you want to.

I always write something on the board to further convey the problem.  I always write it in C, but the interviewee can solve it in their language of choice.

   1: char *s = "10.5|11.1|9.12";

Any of these solutions would solve the problem easily, but only two people have thus far done so.

  1. sscanf
  2. std::cin
  3. strtof, strtod, strtold, atof
  4. strtok combined with something from 3
  5. split

If I cannot get a candidate to make it past these questions what is the point in asking them to reverse a string, or delete a link list.

I was told that I need a blog.  (Actually, I wasn’t, but I read it somewhere.)  So it begins…
