Hi Anon

Congrats on the offer. Here is my take based on what I know but I also think a lot of your questions are basic. Did you not get the chance to ask your interviewers? They would be able to give you far more insightful answers than this forum

1. Knowledge Analyst and the said role is basically the same. Right? - Similar career path and day to day work yes
2. Does it involve working with consultant team on client's site? You often work with consultant team but to be on site is rare in my experience
3. Briefly mention what does the work look like. What kind of projects/research work are expected to be assigned in 1st year considering one has prior experience of 1-2 years working as a financial Analyst? Depends on your team
4. What are the working hours like for this position? Typically decent - 9-6 perhaps
5. Does this position involve any travelling? Very rare
6. How does a typical day look like for this position? Again one for your new team
7. Anything to prepare for beforehand so as to excel in this position? No
8. Is there a chance to move to Associate/Consultant track from this position later on? Yes I have known consultants who made the jump from Knowledge to Associate track but again this was not common. Plus I said earlier lifestyle is 9-6 but if you want to move to the Associate career track - you will need to put in the hours to impress your managers and make the transition

Best of luck
