I’ve been heavily involved in interviewing recently, both as a candidate and offering advice from the “other side of the fence”. I’ve been spending a lot of time working out in my head exactly what the best way of interviewing is. Below is a summary of what I’ve come up with so far, with each point to be extended in later posts.
- Decide exactly what you’re hiring for, the role and the tasks to be performed by that role.
- Test for aptitude, not specific knowledge.
- Questions need to be fair: if you’re going to ask for very answers to very specific things, then consider sending the candidate an outline/”reading list” before the interview.
- Remember that a good team has a mix of people, skills and backgrounds.
- Expect no more or less of your candidate than you expect of yourself – that includes turning up on time, a certain level of dress, the ability to answer questions, particular technical knowledge, etc., etc.
More to come.

Simple, first of all create a variable that contains (n*m) elements
> a = rnorm(100*100, mean=100,sd=1)
then dimension it
> dim(a) = c(1000,10)
where the first parameter is the number of rows, and the second the number of columns. Easy.

I am using R quite a bit at the moment and found a useful snippet of code to generate random “coin tosses”:
x <- sample(c(-1,1), 1000, TRUE)
