Interview Questions and Answers: Problem Solving Questions
Problem solving interview questions should be expected in nearly
all job interviews. They're directly related to assessing job
skills. They're often real problems for interviewees.
Unfortunately, many interview answers just don't measure up.
Employers need to see a clear demonstration of job skills, and
this interview question is very important in that regard.
Problem solving is a direct indicator of skill levels. A good
interview answer needs to show a level of problem solving skills
which is suitable for the job.  Many people sabotage themselves
answering this interview question, simply by their choice of
subject for their examples and not communicating effectively.
The common mistakes in interview answers are:    • Picking an
unsuitable example for the interview answer   • Using examples
which don't show the right level of skills   • Interview answers
are disorganized, not well explained   • Interviewers don't
understand the problem or solution
