The phone interview took about 45 mins. The interviewer and I went to the same collaborative editing website. The interviewer firstly asked some questions about my resume and then asked something about the Linux commands, then introduced a question related to the implementation of the command. After that, the interviewer asked an algorithm question. Finally, I asked the interviewer a question.

Overall, it was a positive and professional interview experience, though the interviewer was on the stricter side. Unfortunately, I was dealing with an illness and wasn't able to prepare as thoroughly as I wanted to, which left me feeling a bit off throughout the conversation. Despite not feeling my best and facing a tough interviewer, the process was well-structured.
