Overall well professional way of approaching. There are 4 rounds of interviews. I was contacted by the recruiter via LinkedIn and had around 30 min interview call. This discussion about the experience , job roles and responsibilities. 2nd interview with the delivery manager, It's most likely to check management skills, agile and experiences , No technical questions. 3rd interview about the technical interview. Technical questions like design, coding, testing,  security , deployment, etc. 4th Interview is a case study presentation for the architecture design and questions were asked about the design approach , security, deployment,  customer interactions related, etc.
