I applied through an employee referral. The process took 3 weeks. I interviewed at Citi (London, England) in July 2022
Interview
3 rounds of technical interviews, followed by 2 team-fit interviews. The technical interviews mainly focused on the technology stack that I would be working on, what my strengths and weaknesses were. There was an element of pair-programming with one of the developers in the team where we went through a use case and I explained my thinking and approach.
Interview questions [1]
Question 1
How would you improve the current development and release process to increase throughput and improve stakeholder confidence and transparency? What are the main advantages and risks when implementing your changes and how would you manage this
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.

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.

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