General Questions

Sometimes, rather than wanting to know if you know specific information, interviewers want to see how you might attack problems in general. Here are questions of this type:

Describe a difficult problem you have had that is programming related. How did you eventually solve the problem and what steps did you take to solve the problem?
If you did not know a skill needed for ajob you were working on, how would you go about learning the skill to finish the job?
What programming practice/habit of yours has later forced you to spend more time debugging your code? How have you taken steps to get rid of this habit? Has it worked?
