Summary
I interviewed for a Senior Software Engineer role at Revolut in Dubai and was ultimately rejected. The process highlighted their strong preference for Java experts with payment gateway system experience, which I believe was not fully clear from the job description.
Full Experience
My interview process started with an initial HR round where we discussed the job description and the overall interview structure. The HR team was quite helpful and gave me a good outline of the question scope for each upcoming round.
The next round was a coding challenge. I was tasked with designing a load balancer for 10 servers and had to write comprehensive test cases for it.
Following that, I proceeded to a technical discussion round. Here, I first implemented a Java method to process a payment transaction, moving funds from Account A to Account B. The key expectation for both this and the subsequent part was to write production-ready code, as if it would be immediately deployed – a pretty high bar for an interview scenario. Afterward, I was asked to convert the exact same payment transaction logic into an SQL implementation.
Ultimately, I received a rejection email from HR, which included detailed feedback. It specifically highlighted my inability to produce a production-level SQL version of the payment transaction problem, which contributed to the rejection.
