They told me that I come across as too "junior" in giving explanations despite my years of experience. This is a really useful factoid for you. You should at least try reviewing one of your past performances for "opportunities to have sounded like a senior engineer" and then, during your next performance, dial that signal to parody levels. If how to do this is not obvious to you, a trick: explicitly verbalize more of your reasons for not doing obvious alternate approaches. Bonus points if you can make those reasons sound like they were won by working on systems operating at scale.
