It's not at all suggestive of gender bias. Just because something happens to a woman, does not indicate in any way that the thing happened to her because she's a woman (unless it's something that couldn't have happened to a man).
I completely agree that there is evidence that the glass ceiling exists, and there is ample evidence of a strong gender bias in society at large that is amplified in certain industries. If you re-read my original comment I didn't dispute that. All I'm saying is that her anecdote is not evidence that she was hitting the glass ceiling.
