I've also seen self-proclaimed senior programmers take more than 10-15 minutes to write a solution.ĭan Kegel had a similar experience hiring entry-level programmers:Ī surprisingly large fraction of applicants, even those with masters' degrees and PhDs in computer science, fail during interviews when asked to carry out basic programming tasks. Want to know something scary? The majority of comp sci graduates can't. Most good programmers should be able to write out on paper a program which does this in a under a couple of minutes. For numbers which are multiples of both three and five print "FizzBuzz". But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". Write a program that prints the numbers from 1 to 100. An example of a Fizz-Buzz question is the following: So I set out to develop questions that can identify this kind of developer and came up with a class of questions I call "FizzBuzz Questions" named after a game children often play (or are made to play) in schools in the UK. write a implementation of a linked list).
How to make a computer program that regularly code#
The author he's referring to is Imran, who is evidently turning away lots of programmers who can't write a simple program:Īfter a fair bit of trial and error I've discovered that people who struggle to code don't just struggle on big problems, or even smallish problems (i.e. I repeat: they can't write any code whatsoever. Like me, the author is having trouble with the fact that 199 out of 200 applicants for every programming job can't write code at all. I was incredulous when I read this observation from Reginald Braithwaite:
