Contacted by HR recruiter for phone screen; additional 1-hour phone screen by hiring director, then 4-hour interview with 4 very personable gentlemen in main office. 1:1's were pleasant experience

I am currently interviewing with the company. I applied online, and was contacted by a recruiter in HR. After the phone screen where I provided an overview of my skills and job history. The recruiter briefly described the company, current initiatives, and compensation expectations. At the conclusion of the call, I was told that there was a 3 step interview approach. The first step being the phone screen, the second a phone interview, and the 3rd an in-person interview, all contingent upon the hiring manager deciding if you progress through the stages after reviewing the feedback received. I have completed the phone screen and phone interview and I am now confirmed for a 3 hour in person interview. The phone interview was a 45 minute long conversation, where I gave another manager an overview of my experience, then we did a case study, and then we left a few minutes for her to answer any questions that I had.
