It was an phone interview. Called me directly on my phone number. The interviewer started talking about the role of the position and the duties invloved. Then it was just a technical interview based on the tehcnical skills required in the role. Interview lasted only 15 minutes.

I was a phone interview, that took about 20 minutes long. Most of the time an interviewer spent talking about position and responsibilities, made sure I understand the role. Very polite and understanding. Asked a few very easy technical question about linux kernel, bash, and java, command line arguments, memory. Then he asked me if I had any questions, I asked about what language do they code onm he answered mainly java.
