Syncroness Software Engineer(Internship) interview questions

First had a phone call. Guy was really nice, just asked me about stuff I had on my resume and general career path stuff. Then I had an in-person interview with two engineers. Kinda weird honestly. They asked me pretty easy questions, no actual whiteboarding involved. One was a simple bit mask question which I know I answered correctly b/c I literally looked up the exact question before. They said I had the bit shifting backwards. Didn't make much sense honestly, I even looked it up after. Then the guy asked me about polymorphism. I gave him an example of overloading which he said wasn't polymorphism (again, really confusing and I had to check myself after the interview to see if I was going crazy) and he noted he wrote me down as "familiar but not well versed in oop". Then he kept mentioning the app I was developing and wanted to look at the code live. I was happy to explain/answer anything he wanted, but I couldn't really show him because 1.) It's an ios app and I didn't have it readily available on my windows laptop, and 2.) It was part of a group effort that we were planning on releasing, and I didn't feel comfortable showing it. He asked me several times and I just kinda gave a nice excuse not to. Just kinda weird, this was for an embedded role. He could have also asked to see any other project (there were 4 on my resume) that were much more related to the role - I mean, he was apparently a C/C++ expert and he never asked to look at my C/C++ code. He asked me what type of programming language I liked the most. I mentioned that currently I was learning Scala and was really loving how clean it was. He responded "Oh you're one of those hipster coders" - like what? Dude, I'm a student that's exploring new coding languages and excited to talk about a new one I'm learning. Anyway, the rest of the questions were pretty easy and simple. I got through everything despite the 3 hitches described above. Just stayed positive, w/e. I got a machine response a couple days later saying they moved on without any other feedback.
