That seems like a realistic interpretation to me, but nothing in particular about what you've written here is leaping out at me as an explanation, not that such a small sample would be terribly reliable anyhow.

You may want to see if you can find someone to meet in person to discuss this matter. Such things may only come out in person. Someone who has been in an interviewing position at a larger corporation would be ideal. You may have to troll some meetups or something for this, which isn't exactly a waste of time when it comes to trying to get a job anyhow, so it's efficient.
