LSEG (London Stock Exchange Group) interview questions

i applied for a role and got the interview HR first round in less than 48 hours. Pretty standard 30 minute online call that was scheduled and confirmed fairly quickly.

In total, 3 rounds of interviews. First one is with HR, basic questions on career motivation, salary expectation etc. Second round is with some team leads in Asia. Quite pleasant communications regarding past job experience. It will be great if you have some relavant experience on Saas platform. Will also ask you some behavioral questions. Last round will be a product demo will ask you a lot basic financial questions approximately last 1 hr. Need to be well prepared. I felt good and confident during the interview, but do not know why didn't get an offer.
