I had a phone interview that took about 20 minutes. Most of the time, the interviewer spent talking about the position and responsibilities, ensuring I understood the role. They were very polite and understanding.

They asked a few very easy technical questions about the Linux kernel, bash, Java, command-line arguments, and memory. Then, they asked if I had any questions. I asked about the languages they code in, and they answered mainly Java.

Name any known command line arguments. What is a Linux kernel? Difference between a class and an object. How to check memory usage in Java. How to search for a word in a text file.
