1. For Hackerrank, there were 10 questions covering topics related to Ubuntu Linux, webserver Apache, Nginx, as well as some questions on Configuration Management (Ansible). There were also questions about designing systems in a cloud environment, such as how to design the flow of multiple virtual machines within a VPC and implementing load balancing. Finally, there was one coding question in Golang, where I was asked to create a function for traffic routing, although I don't remember the specific details as I provided an incorrect answer for this question. 2. During the phone call interview, we discussed the various stages of the interview process at Tokopedia. I introduced myself and provided an overview of my background, including some technical aspects of my work. 3. In Technical Interview 1, after the initial introduction, I was asked about my day-to-day responsibilities. They inquired whether I had experience with Linux environments, hypervisors, and infrastructure-as-code tools. 4. In Technical Test 2, I was asked questions related to high availability, specifically regarding hypervisors and virtual machines. There were also questions about Ubuntu Linux and its command-line usage, networking protocols, containerization, Kubernetes, and monitoring tools. Towards the end of the interview, they also asked if I could code and which programming languages I was comfortable with. That's about it from my side.
