I applied online. The process took 4 weeks. I interviewed at Citi (De Zoom) in Sep 2022
Interview
Was contacted by email to schedule an interview after applying from LinkedIn.
Had a first interview through Zoom, then a second interview through Zoom with a panel of experts and management.
Everyone was very respectful and very nice to me.
We had a conversation based on questions which varied from Technical knowledge, application on Data Science and personality questions about how I work with a team and how I face difficult problems. In general the complete process took about 1 month and it was a very good experience for me.
Three rounds of interview in total. The first interview focus on more technical or role- specific questions. The second round is case study presentation. Conversations shift toward company values, leadership alignment, and cultural fit when you near the final stage
3 rounds, 2 technical and 1 hr
Technical on basic ml and rag based
Decision trees, random forest,etc and classic rag structure, vector db, llm, etc
What the heck why is it asking so many words
Two technical round and a hr round. Asked questions from resume, ml projects, gen ai, llm, rag etc. Asked if I have done some courses in ml and dl. Before the interviews there was an online test consisting of aptitute and reasoning questions along with data interpretation.
