I had an attending on medicine (who I happened to be placed with for 4 weeks) who hated my presence from essentially the first day. She was from New Jersey and I am from the South, I wear pink and she thought pink was silly, I got ready in the morning and she showed up with wet hair, etc. So before actually getting to know me, she made an instant judgment of the kind of girl I am and made it known. She asked me (more than once) whether I had even passed Step 1 (always after asking me the most ridiculously obscure question). There was never a day where she didn't find something wrong with what I was doing. She critiqued every little thing that I did-my interviewing, my note writing, my walking speed, you name it-she had an opinion. I was terrified what would show up in my medicine evaluation. She wrote a GLOWING evaluation (probably the best one I got all year). That may not be the case for everyone but she rode me the whole rotation and essentially wrote how well I did under pressure, how willing I was to work, etc. and offered to write me a LOR this year. SO, it may not be the same for everyone, but that's what happened for me.
