I applied online. I interviewed at Bloomberg (London, England) in Oct 2019
Interview
Stage 1: HR filter round - pre-recorded video interview where the question shows up on the screen and you record yourself (computer mic & camera) answering it
Stage 2: On-site interview with the Infosys team leaders
Stage 3: On-site interview with the manager further up the chain
Not sure if there are more stages as I was unsuccessful.
Overall a very pleasant experience both with their recruiter and on-site interviews. Great office by the way!
