Phone interviews consisted of plethora of technical questions. Although from being a Enterprise Application Integration background, I was able to answer most of them, They were ranging from SAN/NAS differences, network debugging in LINUX, cases of troubleshooting in a "hybrid cloud" environments, UNIX commands, RAID basics, my previous work experience, my interest in cloud and any personal or professional experience there. Onsite interview were more focused on behavioural and situation based questions. It also involved some technical questions such as SQL/NoSQL, architectural questions, "Tell me about a time" questions, etc.
