I applied in-person. The process took 2 weeks. I interviewed at Citi (São Paulo, São Paulo) in Jun 2009
Interview
The interview is so hard, so technical details is required. Strong technical skills are needed. You must be updated to the Market and to the latest technologies in the IT Programming. Don`t be nervous and do not lie, they`ll find your lie.
Interview questions [1]
Question 1
Details about C#, Static class, static variables, etc.
Details about SQL server, about Transactions, about transaction log behaviors, etc
Details about WCF and Remoting technology. You must be very skilled programmer.
Design and scenario based questions, not straight from theory or books. Keep your concepts clear in programming and skills for developer roles. I applied for senior role, more questions they were expecting were in distributed architecture, complex KARAT coding etc.
Interview questions [1]
Question 1
System design questions, related to event processing for communication between different microservices.
The initial interview round is conducted by Karat, a third-party technical screening company. You will participate in a live, person-to-person online coding assessment to evaluate your core engineering competencies. All in all, it was good.
I applied online. I interviewed at Citi (London, England) in Feb 2026
Interview
Easy first round they use screen tool to ask you write some code. Second round is scheduled then got cancelled saying they will not proceed further? Waste of time in my opinion, also the interview person has nothing to do with the role you apply for.

Question 1
Figure out a bug in the code.
Then write a small method.
