The Hammers had a 2-0 lead after 11 minutes, but Hull managed to bounce back and had the lead by the break.
Manuel da Costa secured a point for Zola’s men in the 69th minute.
“It was a crazy game,” Zola said. “When we were 2-0 up, I couldn’t see them coming back because we looked in control.
“Their first goal was a deflection, maybe the second goal we should have done better and the third goal was a penalty that wasn’t a penalty at all.
“After that it was tough to come back but the reaction from the team was excellent and I am delighted for them.
“Maybe we could have handled it better when we were 2-0 up but I have to say they came back really well.
“At the end of the day we have got a point and it could have been more because we had a couple of chances to get another goal.”
