Applied online, very quick follow up from recruiter asking whether I'm interested to proceed with phone screening. Then my application was forwarded to another recruitment co-ordinator who emailed me about the day and time preference with a few choices. Next step, phone screening. The guy who interviewed me asked to rate myself in a different areas like server administration, Linux, database etc. He was easy to talk to, very polite and didn't rush. Asked if I had any experience in AWS, and moved on to windows server (DNS, Event Viewer, FSMO, Group Policy), cloud computing basics, database (back up types), TCP/IP (TCP vs UDP, 3 way handshake, storage, virtualization, Routing protocol are the few I could remember. Not very difficult. Since I didn't have much experience in Linux and database, and hadn't answer most questions correctly in that area, I was not selected to the next round. But very good interview experience. Took about one hour.
