so You Mean to tell that certification is all waste.....
It depends. As the old saying goes, "You get out of it what you put into it."
If you're just looking that piece of paper that says "I am certified," then the certification may get you in for the interview and may even get you the job... until they figure out you don't know what you should know. Then you'll be looking fo a job real quick. Enough of those short stays on a resume and people won't consider you any longer.
On the other hand, if you use certification to help you gain more knowledge, then that will come through, both in the technical interview and on the job.
