AnyaKimlin's examples--which are excellent--point the way. She gives us not merely descriptions, she tells us how the character moves through them, reacts to them. A character paints his house every five years. That raises a question--why so regularly? And paints it the same color. OK, now that's really odd. An OCD person, very possibly. The flatscreen TV his sons bought and a recorder that is useful when the grandkids stay over--a statement that establishes the character's and shows an aspect of his personality in a single sentence.
That's a hook, because it gives the reader something to react to. The hook is like a bit of movement in the forest, or down the street. What was that? Did you see that? Hear that? A person's first instinct is to look again, to listen more closely. That's the hook. Now you have to deliver a character worthy of the hook.
The OP asked about that. There are tons of guides; I recommend getting a few. One or more will resonate. My own contribution is this: I have to care. Before the reader can care about a character, I have to care. With a principal character, I usually have some feeling about them right from the first, but with secondary characters it can be something of a formal exercise. I write backstory, and this must be more than mere narrative. I specifically look for conflict--setbacks, difficulties, even trauma. I look for triumphs as well. I try to get to a point where I imagine someone criticizing that character, or praising them, and I come along and say here, let me tell you about this guy. Here's why he's like that. And here's something I bet you didn't know. I need to be able to gossip about them.
This emotional involvement is crucial, for me. If I expect you to care, I must care first.
