I applied online. The process took 4 weeks. I interviewed at Visa Inc. in May 2024
Interview
Interview consist of online CodeSignal assessment with 4 random problems, one of them easy, two medium and one hard. The last problem was really hard and required you to know Line Sweep algorithm in order to solve it. I managed to solve but not optimally, received 550/600 points. Fast forward that was the only challenging part of all interview process, everything else was pretty easy, so overall I would rate interview difficulty as easy.
The second round supposed to be live coding, but for some reason I got System Design question - variation of distributed view/likes/transactions counter. The third round was also System design, basically rate limiter. The last one was behavioural, which I seem to fail. I haven't received a proper feedback, so I don't really know the exact reason.
It seems unfair, because I spent a lot of time with all this interviews and at least expected to receive a proper feedback so I could improve lacking skills. Instead I literally got "We’ve reviewed your background and experience and unfortunately, we have decided to move ahead with other candidates". Not cool, Visa
Interview questions [1]
Question 1
Design transactions counter with high load of requests
3 hacker rank questions for the first round of tech interview. Medium to hard level.
You need to solve them in around 2 hours. Didn’t pass the this round and received the rejection after few weeks
One coding, Recruiter round and a loop round(3 interviews). I got the feedback on the very next day of my loop round and later they have done a reference check with my current manager and colleagues and then released a formal offer letter
Online assessment round is first round with data structure and algorithms with array sorting algorithms on hacker rank which was moved recently. There were two questions and they were very very difficult
