Today I have to do a test for programming skills for one of our potential clients. There was very interesting questions for short time. For example I had to implement a stack for 3 minutes in any programming language! My observation from this experiment is that you can’t say that you know some programming language if you can think on it. I am using Java more than a year but for this test for time I would not even try to implement the tasks in Java! So next time when you think that you know some language just implement something relatively simple for 3 minutes. π
