How many days does it take for CNOOC to recruit fresh graduates in 2015 and go to interview?

I have seen CNOOC come for an interview. I gave the message at 5 pm yesterday and came the next morning. They just said it was CNOOC and did not mention the specific company. I just let anyone who had any connections know. The solution is to have two rounds of interviews, which ended in two days, and then within a few days, a notification was issued to sign the agreement! I have seen an oil service interview and it was all done in one day, and I signed on the same day!
