Phone screening was mainly about my experiences with AWS and recent migration projects I was in charge of. He covered various topics in DevOps and .NET development as well as SQL questions within AWS environment. He made me feel pretty comfortable and he told me many positive things about Slalom which is always nice to hear from someone who's considering working there. Whiteboarding sessions included more in-depth modern s/w design concepts (DI, REST WebAPI, Redundancy, Resilient design etc) They had me design architecture diagram for my recent development projects as well as generic web server environment in AWS followed by detail questions to probe my knowledge and understanding of the architecture. They also asked a couple of container questions as well.
