TailorMed Software Engineer interview questions

It felt like the guy didn't have time to interview me and just wanted to get over with. He asked me unclear questions like: "did you ever encounter performance and/or scalability problems". I said sure, but there are a lot of problems related to scalability/performance, cloud you be more specific. then he didn't direct me where he wanted me to go, so 15 minutes went by pretty quickly, and that was it. very weird interview.
