Java technical interview guide - part 1

update 8/31/05: I have written part two with some possible answers. Also, renamed the post.

I did a technical evaluation for a candidate my employer was looking at awhile ago, so I had an opportunity to try and figure out a good set of technical questions for a prospective intermediate level Java web developer. I’ll just present a whole bunch of questions I came up with - no answers though. I might start up an answers post at a later date, but I don’t want to make this too easy for those trying to fool interviewers. =) Obviously, if you ask every question I have listed here your interview could take hours, so pick and choose what you like. I’d be interested in feedback for ideas on important topics I’ve overlooked or questions that are unfair or unnecessary. I’ve tried to avoid things that can be easily answered with a quick google search, such as basic syntax and API method questions.

Anyways, on to the questions.

General Intro Questions

Just laying the ground work to help lead the way for areas to focus on…

* Give me a high level description of your experience with the Java platform. What APIs do you have experience with? Servlets? J2EE? Swing?
* What development methodologies have you used? Which one have you liked the most? The least?
* What open source frameworks do you have experience with?
* What other languages have you used?
