I am currently pursuing a career in Cognos and need your
support in the same regard. I am in the position that you
were in as described above. I would like you to share your
experience during interviews, project explanation, on the
job etc. I am preparing for the interviews and am quite
nervous about cracking it. I am sure you understand the
anxiety. Your help will be greatly appreciated.
Awaiting your response!
