Siddhartha (Project lead)

I've attended the Informatica and Cognos sessions at JJ Mentor Data Warehousing Solutions. What impressed me most was that Prasad is a terrific teacher. He has a tremendous working knowledge of the Informatica and Cognos and also the ability to convey that knowledge in a logical, approachable manner. Some of the more difficult topics of Informatica and Cognos which can be challenging, Prasad helped us de-mystify the process by breaking things down into clear and simple steps. Prasad has a friendly, easy-going demeanor and a patient sensibility that also helped calm any anxieties we had, which proved instrumental in our learning process.
Above all, Prasad's love of teaching comes through. He's able to challenge us as students and help us find our way in a very reassuring and supportive fashion. He's not just out to flex his superior knowledge, he wants us to understand the principles of how to use informatica and cognos .To be honest, I couldn't have asked for a better mentor and each moment spent in class with Prasad has been a constant learning experience.

About Prasad

Knowledge to the care
Sincere and Helpful.
Very patient


I am student of JJMentor; my personal feeling is JJMentor is a good institute to learn data warehousing tools and its concepts. I joined for cognos which is very good .Prasad sir also explains the subject in a way that you get confident about the topic and the subject. He also gave us complicated scenarios which u may face them in the real time. he provides material and he also gave the notes in the class .

Prasad sir is very decent and his way of communicating with students is also quite good.He cares for each and every student in the class and check with each student whether they are able to follow the subject he is teaching. No one can find this type of teaching in any other institutes......Its like spoon feeding.

This is a right institute for fresher's and also for the people who are working. Prasad sir will help us to face the interviews, kind of questions u face in the interviews I recommend this institute to everyone who wants to learn the cognos.............


I came here for training with no knowledge on data warehousing. By the end of the course I gained good amount of Knowledge.
