Can anyone advice if the tester do ITIL certification whether is this useful for his career or not?
If it is useful how this will help for his career?
For me, I think all the certifications will be useful at the time, while searching for a new Job. It will be an added advantage to your resume, but not to your personnel knowledge.
ITIL v3 you can do ... fee is near about +/-9k I guess....
It will give you at least a new perspective ( and might be recognition too )...
Some companies will require you have it, some will not. Never a bad thing to learn it but again a 'certificate' isn't always required and in those cases a basic elearning to gain the basic concepts would suffice - if its not required for your role or company.
