SailPoint Technologies Developer interview questions

Scheduled a phone call with the hiring manager. There were a few behavioral questions asked and no technical questions asked - revolved mostly around knowing cloud technologies they listed on their posting.

Probably the strangest and most unprofessional interview I've ever done. The internal recruiter was unresponsive and didn't answer a question I asked. The person I talked to for the screen was either completely unprepared or not interested in doing it. Without saying a word about the company, the team I was applying for, the product, or anything else, he immediately starts peppering me with various detailed questions about my past projects, seemingly just to see if I could answer them, including things like what level of test coverage did I achieve for something I worked on four years ago. He then gave me a programming problem, which he wanted me to do in a Google doc (!!!). All throughout this I'm asking for feedback and trying to get a sense of whether I'm solving the right problem, he just responded with monosyllabic noises of approval, and abruptly cut me off after ~15 minutes, finally giving me a chance to ask questions in the last 10 minutes of the interview (like what will I actually be working on). Don't waste your time with these people.
