Joe,
Welcome back to the job market!
The
SCJP FAQ offers useful information on the certification.
If you are just returning to the job market then studying for the certification will be a helpful review and will certainly be a great preparation for any Java exam that you might have to endure during the interview.
Questions such as yours are frequently covered in the
Jobs Discussion. Most everyone that participates in this forum are believers in certifications otherwise they wouldn't be here. Some of the participants in the Jobs Discussion forum have a differing opinion. From my point of view, the knowledge acquired during the preparation process for the certification has value regardless of the value of certification itself. In other words, it's a great learning experience.
