The online test was a Hackerrank exam with 3 questions. Standard LC medium question on number of nice substrings of a string, second question was about calling an api endpoint, and then extracting & processing some data from the response. The third question was a hard SQL query. I received an invite for the first technical round following the test. The first round was DSA based. Graph(BFS based search), Binary Trees(sum root to leaf numbers), and Edit Distance problems were asked. The second round was more of a System Design round. I was asked to write the interface and some scaffold code for a Job Scheduler (with context for job cancellation/suspension/addition/queued jobs). The hiring manager round had a thorough discussion of my role at the previous company. We went over software design choices , failover scenarios, resiliency - in sordid detail. I was also asked to design api endpoints for a simple web app, and talk about principles of secure api design - not sending unencrypted data in request/response headers, and other security aspects. Finally, I received an email telling me I'd been selected, and an invite to the HR discussion.
