Three rounds, two technical rounds and one manager round. Two technical rounds are in medium difficulty in average. Manager round is about bq and resume questions. I got the offer and not accept
Really pleased with how everything turned out. The experience was straightforward and less stressful than I expected. After a quick chat with HR, I jumped into a technical round where I faced a coding challenge on counting distinct island shapes in a grid. Funny enough, I had practiced a similar problem on PracHub just a week earlier, which made it a lot easier. Overall, the interviews felt well-structured, and I received an offer soon after. Happy to say I accepted!

Right now I’m talking about the OA process. The questions are all from CodeSignal, and since CodeSignal has a question bank, there’s a high chance you’ll get a problem that has appeared before.
Questions d'entretien [1]
Question 1
The first two questions are quite easy, while the last two are more challenging. It really helps if you’ve seen them before. One key difference from LeetCode is that the problems are usually much longer in description, and they rarely test dynamic programming.
