The Post’s Steve Serby chatted with the 6-foot-9 forward from DePaul who was the Knicks’ first-round pick in Thursday’s NBA Draft:

Q: Three dinner guests?

A: (DePaul coach) Jerry Wainwright; Coach Isiah; my grandmother (Olivia).

Q: Why your grandmother?

A: She raised me very well and always taught me what was important.

Q: Best advice your grandmother gave you?

A: Be myself no matter what. Always be a good person, be respectful to everybody, go with the flow.

Q: Why did your grandmother raise you?

A: My mother and father had problems and thought it was best for me to live with my grandmother.

Q: Describe your grandmother.

A: A soft-spoken person. If I did something wrong, she’d get on me.

Q: What would she discipline you for?

A: A “C” or “D” on my report card . . . cleaning my room. My grandfather was more of a forceful person. She talked to me one-on-one.

Q: Was she at the draft?

A: She doesn’t fly.

Q: Why Jerry Wainwright?

A: He became a father figure to me.

Q: He suspended you for two games when you were a freshman for what was called “time-management issues.”

A: I was late to practice once. I think I went home to see my mother. I told him I’d be back on time. I should have left early enough. At the time, I didn’t think it was fair.

Q: And now?

A: It was fair. I shouldn’t be able to get away with it.

Q: Did you miss not having a father growing up?

A: My father’s always around. I never had any bad thoughts about my father. I talked to him (Thursday night) after the draft. He just told me, “Congratulations.” He’s happy for me. It’s my dream.

Q: The first time you played in the Garden?

A: I didn’t have a very good game. But just to be in the Garden was wonderful. It’s the world’s most famous gym. But it’s different when you’re playing for the Knicks in the Garden.

Q: Stephon Marbury?

A: Great scorer, great penetrator. He can make shots for everybody else.

Q: Eddy Curry?

A: Great low-post player. A lot of offensive tools. He’s gonna be way better this year.

Q: Zach Randolph?

A: He can move well for his size and get you 20 and 10 every night.

Q: David Lee?

A: Great athlete, hard worker, energetic, runs up and down the court.

Q: Wilson Chandler?

A: Very athletic. I try to play hard, try to be a good teammate, sacrifice my personal goals for team goals.

Q: Isiah Thomas?

A: Cares about his players off the court as well as on the court. He’s gonna turn the program around.

Q: Spike Lee?

A: I met him after the draft. We shook hands, he welcomed me to New York. It was just a great honor to shake his hand.

Q: Where did you start playing basketball?

A: Fairplain East Elementary School (in Benton Harbor, Mich.).

Q: How old were you?

A: Fifth grade.

Q: Childhood dream?

A: Basketball’s the only thing I ever wanted to do. I still don’t know how to swim very well. I never learned to skate. I thought I was gonna play basketball.

Q: Did you have a favorite playground?

A: Across the street, Junior Park. I had a rim in my backyard. I shot around by myself a lot.

Q: Whom did you pretend to be when you were alone?

A: Michael Jordan, Scottie Pippen. My grandmother talked about Isiah a lot. She was a Michael Jordan fan but the Bulls couldn’t beat [the Pistons] back then. She’d always say, “It’s gonna be tough to get past Isiah.”

Q: Whom did you like to watch later on?

A: Allan Houston, Jamal Mashburn when he was on Dallas.

Q: Why Houston?

A: He was a great shooter. When they went to the Finals against the Spurs I watched a lot.

Q: Do you have any nicknames?

A: Some people call me Will. A couple of my friends call me Ill Will, but it never had meaning behind it.

Q: What about Will The Thrill?

A: My high school coach gave me that name. I’m a laid-back person off the court, so it was kind of a joke.

Q: Sounds like it’s a better on-court nickname.

A: At first it wasn’t an on-court thing, but everybody thought it was.

Q: Favorite dunk?

A: Against Notre Dame. There were 13 seconds left and my teammate (Draelon Burns) stole the ball and I dunked at the end. It was the last basket in the game for the win.

Q: Most thrilling dunk?

A: Wake Forest. I made “SportsCenter’s Top 10” . . . No. 3. I missed a jumper, one of my teammates got the rebound, he passed it to me, I went up for a layup, we went chest-to-chest, and I dunked it.

Q: What’s Benton Harbor like?

A: A small town. Everybody knows everybody.

Q: Did you go to your senior prom?

A: No, I don’t like to dance (chuckles).

Q: Favorite movie?

A: “He Got Game.”

Q: Favorite actor?

A: Omar Epps.

Q: Favorite actress?

A: Halle Berry.

Q: Favorite entertainer?

A: Jay-Z.

Q: Favorite meal?

A: Pepperoni pizza.

Q: What message do you have for Knick fans about what they should expect from Wilson Chandler?

A: A player who’s gonna come in and do every little thing the team needs him to do – cheering on the bench, getting hustle plays. I’m gonna try to make everybody proud of me.
