BlinkHealth / BlinkRx Interview Experience
Summary
I went through four interview rounds at BlinkHealth/BlinkRx, including an online assessment, high‑level design with AI‑assisted implementation, a design discussion, and a final HLD/prior project discussion.
Full Experience
Role: Senior Software Engineer
Round 1 (OA) (Hackerrank) 10 MCQ (5 SWE + 5 AI) 1 DSA (Medium/Hard) 1 API Development 1 Prompt Engineering (Optional)
Round 2 HLD + AI assisted Development Create an Idempotent layer on top of a service for operation like Order create such that if the client sends multiple order create events we should be able to handle this idempotency. Interviewer asked to implement the same using AI Agent of your choice.
Round 3 Design Discussion If you are supposed to design a medicine development platform how will you decide the microservice bounderies, what sort of communication each of these service will have? Which database you'll choose at per service level? If Asyn communication is there which tech you'll opt? Do we need AI for any serice ? If yes! how can it help ? etc etc
Round 4 HLD + Prev Project Discussion Design a system similar to ServiceNow for raising support tickets and follow up question on previos project design and tech choices.
Interview Questions (2)
