I have a coworker who is vocal and very assertive when he thinks something is being done wrong. We're both mid-level developers, but he is a much more experienced developer than I in the language that we're using. Hence he often has a lot of critical feedback on my code reviews.
The problem is that I find myself feeling injured when I read through his comments. I don't usually feel like that when I receive code feedback from other coworkers. It's hard to point to specific examples, but his feedback is blunt and tends to have undertones implying that I don't know what I'm doing.
I read the question of How can I be assertive without being rude or offensive? and my question is the other side of the coin in that scenario:
How should I handle an assertive peer who gives valid feedback, but comes across as overly blunt and offensive?
If I can't prevent it, how can I learn to stop being so sensitive about it?
