Colloquio
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

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

I went through the process twice for two separate applications, about 3–4 months apart. The steps were mainly LeetCode, system design, and cultural fit interviews. If you’re solid on most medium-level LeetCode problems, you should be fine.
The process itself isn’t particularly difficult, but I think it’s mostly a numbers game since there are a lot of candidates competing.
The negative part was the communication from HR: constant ghosting and timelines that were never respected. I only found out I had been rejected after my second follow-up asking for feedback, more than a month after the last interview, and only once I started sounding frustrated in my messages.
Applied through careers page, received link for OA. The assessment was on CodeSignal, has 4 questions. 2 are easy, 1 medium and 1 hard. I solved 3 questions completely, did't receive interview invite
