I certainly agree with Amanda on this point... but looking at the code is not enough. (Meaning: I've been fooled by looking at code that the interviewee said s/he wrote.) Just what makes a "software engineer" seems open to debate, also. A typical interview session goes something like: "Do you consider yourself a software engineer?" "Yes." "Why?" "Well look at my resume. I'm not just a programmer. I write code that talks to hardware." Sigh. I think I'd like to find a few software craftsmen about now. The one question that does seems to separate the wheat from the chaff is "define the term: abstract data type." Even the ones that know all the current OOP buzz words (without knowing any of the concepts) seem to get tripped up on this one. "Well, you know... They're ABSTRACT!" -- // marc // home: marc@dumbcat.sf.ca.us pacbell!dumbcat!marc // work: marc@ascend.com uunet!aria!marc

However, sample code is often much more informative than grades or other certifications that are based on some "authority." In fact, I'd probably view an EDP certification as a demerit, on the grounds that anyone who would want one probably doesn't understand how I think of software :). Sigh. I think I'd like to find a few software craftsmen about now. Me too. They are <expletive deleted> hard to find. You can often take bright people coming out of college and teach them well, but finding already-experienced people is very tough. You'd think there wasn't any demand for creativity and excellence in the software industry... But I digress a bit... "Well, you know... They're ABSTRACT!" Many giggles. Sigh. One of the people on my team often asks people to write down the algorithm for "binary search." Amazing how many people this trips up...

I once taught an Intro to Computing class where the tests all consisted of such bizarre questions as: Write a program to.... Most students didn't like this. They wanted me to quiz them over parts of the language. Nobody is paid in the real world to know what some verb or keyword does; we're paid TO WRITE PROGRAMS. So tests mimicked the real world. I changed a lot of majors. My own views are expressed above, /Bill

This is true; however, if I can't see a non-trivial sample of someone's
code (under NDA if necessary), they're not likely to get even so far as
an interview, unless there are extremely convincing extenuating
circumstances...

And how closely do you inspect it? In the years I've been doing this, I've never asked -- or been asked -- to see anyone's code. It's an interesting idea, though. How about this alternative (since not all candidates will be using the language I may choose): Given a problem, let the candidate work out the solution method on the wall with you. One, it gives you a clue to how the individual attacks problems and, two, how they work in a small group. Or this: Given a piece of code, explain what it does and how it could be changed. /Bill

Given that I feel writing software (especially in the age of user interfaces) is very akin to design, I always though job applicants should have portfolios. If not of source code, at least demos of programs they have written (of the actual thing, under a give-it-back NDA). >How about this alternative (since not all candidates will be using the >language I may choose): Given a problem, let the candidate work out the >solution method on the wall with you.

If I can't read Pascal, C, C++, Ada, BASIC, Fortran, etc., what am I doing thinking I have the expertise to hire a programmer? Talk about throwing darts blind-folded! 1/2 :-) >Or this: Given a piece of code, explain what it does and how it could be >changed. For what it's worth, I have seen Bill Gates claim in several places (the most accessible in-print version appears in _Programmers At Work_, by Susan Lammers, Microsoft Press) that this is his standard hiring procedure. In addition to deciphering what the program did, the applicant was expected to be enthusiastic about it. :-} >/Bill Toodles and cheers. -- John Lacey 614 436 3773 73730,2250 john@basho.uucp or basho!john@cis.ohio-state.edu
