I sent my resume to the professor who needed the research assistant. He directly responded to me to set up an interview. I went in the following day and met with him for about 15 minutes. He asked me a few questions and asked when I could start. He hired me at the end of the interview.

The process was pretty simple. I was directly interviewed by the faculty member. Mostly the questions were focused on the description. Previous contributions to research were asked to be elaborated.
