RagaAI Backend Engineer interview questions

Round 1: I was asked two DSA questions: Multiplication of numbers represented as strings A problem based on binary search I was able to solve both questions within the time limit and verified my solutions with multiple test cases, all of which passed. The time complexity of my solutions was optimal. However, I received a rejection email 2–3 days later without any feedback. It’s disappointing to invest time and effort into an interview process and not receive any constructive response. The lack of communication makes it feel like the process wasn’t respectful of the candidate’s time.
