Task Management Service HLD + LLD. Questions around class structure, different components that will be there.
Round 3: Bar Tender. Questions around OCI leadership principles.

Got the feedback that they will have one more round around Design.
Round 5: HLD of Resource inventory service for a cloud provider. Questions around DB schema, search capabilities, sharding decisions, VPC, subnets.
