I applied online. The process took 2 weeks. I interviewed at Citi in Oct 2017
Interview
Applied online and after numerical tests got invited to do a phone interview. Interviewer was nice and asked me a bit about my CV before moving to some behavioral and competency questions
It was a really good interview process that I really liked and enjoyed doing. The first round was very casual and the questions werent challenging in the slightest. It felt low pressure or stress
They asked a mix of behavioral, technical and market questions. Pretty standard interview, no huge curveballs. There were a few brain teasers and mental math questions, no paper pen allowed.
A few rounds of group interview, some with 1 invigilator, some with a panel, and one one-to-one interview. Interviewers appeared stern and not the most friendly, perhaps to give off a sense of seriousness.
