God this is so true it hurts. It's what I've always hated about performance reviews. It feels like an attack on my personally because it's never about my work, it's about my clothes or my face. One memorable experience was when my boss came out of no where and said "You don't seem happy here. You don't smile enough. You're now on probation until you get your act together."

Not one sentence about my work as a software engineer; not one sentence about specific interactions that were problematic, or whether or not I had been reported for anything. Just vague as can be.
