EXL Service Senior Software Developer interview questions

Got a call from recruitment agency, Total 4 rounds of interview, 3 virtual and 1 face-to-face. 1st round consisted basic questions on .Net core, angular, SQL Server and one coding question to remove duplicates. 2nd round was also similar with similar questions around the tech-stack. 3rd round was face-to-face or more of a in-office round because after reaching office it was a virtual interview only. Questions in this round were around Kafka - how to restart kafka if its down and what happens to the messages if kafka is down. Then was 4th round which is client round, basic questions entity framework performance enhancements etc. Have some weird phone policy though rest very cooperative recruiters and friendly people. Matched the comp also. Couldn't join because of location.
