I was reached out to via email and given a link to let them know when I would be available, The next day I got a date and time within the windows I had given with instructions on how to get to their offices in the building as well as who I would be interviewing with.
On the day I interviewed I went in and was met by my interviewers who were very personable and professional and we talked about the job and they asked questions and we got to know each other a little and shook hands when it was done, all in all it was a very easy experience and I'm glad it went so well.
