Third Coast Events interview questions

I got a text saying they want to interview about the role pay and everything between. Hey Austin, this is the HR Team at Third Coast Events reaching out about the full-time role you applied for in Houston, TX (not remote). We would like to schedule a 20 minute Zoom interview with you to go over the details of the role, pay, and growth options with the Hiring Manager.

It had two steps, at first step interview was in an online meet with 5 people, they didn't provide any information about the role and its responsibilities, and after that in second interview which was in-person they told me that this role is 100% comission based which they I wasn't aware of before this step of interviewing.
