I am a DBA Manager for a big company here is NY, I have hired at least 30 dba's
in my career and interviewed hundreds, my experience is if a person is Certified it
doesn't mean that he/she qulified for the job. All my employees are not certified
but they do exelent job.
In my opinion you need to be certified only if you are not
confident about your skills, i.e try to skip techinical interview.
The comapanies does the Certification process exploiting people so they can make money.
just like other certification process GRE, GMAT etc.. (By the way I got high score in GRE though)
Sorry some of you may not agree with me, But it is true and it's my opinion only.
