Visa Inc. Senior Software Developer interview questions

Great and very smooth. HR was in touch with me during the whole process. Technical and managerial rounds did not take much time but background verification process took around a month

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
