Hi Stupida, Thank you for your suggestion but i think i am ready for Informatica brother and i am familiar with most of the mapping, workflow but don't have hands on. I am sure i can handle it but i need to clear the interview or get the job, I am not a fresher with fake resume. I am working as Data Analyst for 7 + years but not as ETL Developer. and they are not looking for 7 years experience or all that, They are looking for 2 - 3 years I wanted to get into Development and that is my interest so i think that should make me qualify right ? Thank you for your suggestion i will try to do some research.
