Hundred software developers interview question
Think employed to engage in software development of smart people is not easy. The event of accidentally, it will get a pile of low-energy large baboons. I met last year on this matter. You certainly do not want to do it. Listen to me, that's right. In a tree stand open door meetings are not.
Ask difficult questions points can help you put smart people with the baboons were separated. I have decided to put me out of their own finishing interviews hundred software developers to question the issue of, I hope to help you a favor.
This list covers the software engineering knowledge system as defined in the majority of the knowledge domain. Of course, if you only want to find the best programmers, it only involves the structure, algorithms, data structures, testing of these topics. If you want to architect-employed, you can only consider the demand for functional design, technical design of these places.
But no matter how you make must bear in mind one thing: the answer to most of the problems here are not right or wrong!
You can put me as a prelude to these questions, discussion. For example, the following have a problem is to use static methods or single-cause cases. If the interview carry out a long-winded, he is likely to be a smart and capable guy! Loss of face if he looked at you, the issue of such voices, it is clear that this is only the baboons. Similarly, a few want to know 2 of involution are not also have a lot of methods, but if people want to interview with mod operator, ... ah ... you know what I mean it. (You do not know if it does not matter to the root of bananas?)
