So do you know what unit test means? You said at the interview you could learn it, so have you? At interviews I loved asking a question I did not expect someone to know, but they would feel embarrassed by not knowing: You know what trees are? <of course> You know what binary tree are? <of course> Please explain... Do you know what a 2-3 tree is? <usually not, so I explain> You know what a balances tree is? <yes> You know what a B tree is? <yes> What is the difference between a Balanced tree and a B tree? <silence> Ok so this seems like a technical question right? Wrong. There are several possible answers: 1) I have no clue (this is acceptable) 2) say something (I will write down every word you say, after the interview I will look it up, because even I cannot remember the answer. If you are right, then good for you, this question counts no more than answer #1, if you are wrong, depending on how wrong, you might be eliminated. I do not need someone who feels such a need to be an expert that they make up stuff) 3) I do not know but I know how to find the answer. (this is really what I am looking for. You will not know everything but should be able to work stuff out. But that only gets you 0.5 points. You must look up the information and email me the answer. 24 hours is as good as 10 minutes after the interview. Although I hate it, it should be in the stupid thank you note. For any skill you do not have but you understand it, try and relate it to something you already have been doing.
