RTX interview questions

First interview was a 30-minute phone call with a Tech Lead. Typical screening questions; asked about my experience, tech stack, etc. Second interview was a 1-hour video call with 3 Tech Leads (including the one from the screening) and a Project Lead. Mostly a behavioral interview with some intermittent technical questions. I'm writing this review about a month later, and have not heard anything back. I reached out twice with no response.
