finished their challenge which required OOD and then was told to do it a JVM language, that was not a requirement in the challenge. The question was to write a class that converts a string and identifying information into an html version of the string that contain tags. This company does not value your time, don't waste it applying.

It started well. I provided basic interface and a couple implementations for the problem in the order, requested by interviewer. Interviewer provided a couple of critique comments about me being inconsistent in terms of names for the classes. I fixed the code according to these comments. But when I tried to combine several implementations in a factory, interviewer asked to "not to write the mess" and I had no chance to finish my idea. At this point I explained that this is not polite to call someone's code "a mess" and decided not to proceed. It took 18 minutes to figure out that I would not want to work with this person.
