I e-mailed someone for more details of a job I was interested in. We had an exchange of several e-mails, ending with me sending my CV, so by the time that was all settled, there was quite a "trail" of messages.
Now I've had another e-mail from him inviting me to an interview - but there's a different "trail" attached to it, in which he exchanges a few messages with someone who is clearly another hopeful for the job. From the way she introduced herself she is probably better qualified than me. We have completely different names and e-mail addresses. DS thinks he must have had both e-mails open and has accidentally forwarded an e-mail from the other woman with a new message at the top for me, rather than replying to mine. But wouldn't he then have had to manually put in my address, which makes it hard to do absent-mindedly?
I couldn't decide what to do so I just replied to the main message saying I would be able to go. Now I keep wondering whether the "mistake" was deliberate to test my integrity - whether I should have let him know that he'd attached something I might not have been meant to read. I could still do that now but maybe it would look odd to have waited so long (I confirmed that I could go last night).
Any thoughts - are am I just overthinking this?
