First phone call was with HR asking a little about my background and talked about the company. Second phone call was with one of the Engineering Director asking more in-depth about my background and my past work, and live online coding question. Invited to an on-site interview with 4 other software engineers (primarily backend folks), VP of Engineering, and Head of HR. Took about a hour each per person. They were pretty accommodating throughout the entire process and everyone was passionate about Trifacta. Definitely a smart bunch.
