I applied online. The process took 7 months. I interviewed at Citi (Warsaw, Masovia) in June 2024
Interview
Phone screen with a recruiter, then an hour long meeting with the hiring manager and another hour technical interview with a team member. People seemed fairly ok.
They came back to me after 6 months of having the technical interview, no apologies, no explanation, saying that the senior position I was interviewing for has been closed, but since I got positive feedback (first time I learned about it) from both interviews, they would like me to interview for the same position but one level below. I decided not to "continue" ;)
Interview questions [1]
Question 1
How was auth handled in the product you worked on previously?
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.

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