Does it Sound Like He's Interested Based on First Date?

Im trying to figure out of this guy is interested in me after our date.. please help me figure out these little things he did and whether they mean he's interested or not

1. We were in our first date & he causally dropped something about a party he was at where he hooked up with a bunch of girls. It didn't really fit into the conversation

2. he would mimic things I would say, basically repeat them back to me. If i pronounced something in a weird way,, he would repeat it back in the same way... he did it a couple times, repeating a sentence or phrase I said

4. he kept wanting me to go into more detail about things I told him about, if I said something that was vague he would be like.. tell me more, what did you do, where did you go

5. he remembered things I told him throughout the date..he also remembered really small details of things he observed about me prior to the date

6. He kept telling me either things that reflected very poorly on him i.e. he told me about classes he failed or things that you basically wouldn't brag about to someone else

7. we stopped by his apartment to pick something up before heading out, and he introduced his roommate/best friend to me but like "Hey this is my best friend______" but didn't introduce me back to the friend

8. the date was pretty long, like 4 hours, but at the end he made some bs excuse about waking up early to get some work done.. which I felt was like a "ok its time for this to end" thing
