How do "pretty girls" get taken serious?

Anonymous
I know this is a stupid question but I feel quite frustrated by this situation. Without trying to sound conceived people consider me pretty and guys hit on me a lot , although I like to have fun and joke sometimes, I also like to be taken serious. I went to a social event in my uni to network and do projects, and I was haunting for people with the skills I need for my project. At first I thougth I was doing well because I got loads of contacts but then has I was talking to a guy another one that I previously talked said " you were talking to me 5 min ago I'm already being replaced" he was joking but at the same time clearly flirting, then another guy while we were switching contacts his friends started to look at him and saying stuff like " woow lucky bastard" and stuff like that, I clearly specify My project and what I wanted and basically lots of guys didn't take me serious and were hitting on me? What can I do to been taken more seriously by the opposite gender ? The last thing I want now is dating I really want to focuse on this
