First OA, then interview with manager which comprised of a bunch of technical questions to answer. Mostly questions on various languages, and technical concepts. Python, SQL, git, etc. asd asda sd
45 minute interview with 30mins behavioral and 15mins technical. Behavioral was your regular situation-based and tell me about a time questions, not too bad. No coding in the technical. The conceptual technical questions they ask are based on your resume and what you tell them about your experience. I had a couple of questions related to REST API implementation, and data structures.
I first got an OA on Hackerrank and I found it easy. Next I got a behavioral/HR screen interview. Did not hear from after HR screen. We went through my resume during the call.
