There were 3 technical rounds and one with HR director. All the technical rounds were taken by manager or higher designated engineers. In the first round I was asked some Golang basics/syntax. Then was asked to write a program to find nearest element of the given element in a BST. In the next 30 minutes he asked a lot of questions about microservices, gateway, service mesh, Kubernetes etc.. second round was on system designing and tools to some extent. Pros and cons of the patterns in microservices, scaling etc. In the 3rd round I was asked mostly about my project, deployment strategies, CI/CD, service mesh etc.
