I've been in the OR for about a year now, we had a 5 month orientation through all of the service lines, and it took me about 6 months to develop confidence in my abilities. It gets much better when you are on your own and begin to settle into a primary service line.
I am more introverted myself, and felt misunderstood at times by some of the extroverted, stronger personality preceptors that I had during orientation. Sometimes, people can see quietness or shyness as "not understanding," though really I was absorbing everything around me like a sponge. The OR was a real learning and growth stretch with me in learning to communicate with others that work differently. I had to ask some preceptors to "step back" at times so I could have the opportunity to take charge of the room, and prove myself. I had to verbalize more with some people, to work more effectively, so that we were all on the same page. I think its good to have a mix of personalities in the OR, we all need to balance each other out, but assertiveness and productive
communication is a must.
With time your confidence will grow, and you will get better at working with all types of people. You will have your chance to prove yourself, just hang in there. Work hard, be a team player, and with time you will be more appreciated.
