Did I hurt my chances?

<p>Just got an email from a recruiter to schedule an interview and to call them or email them back so I tried calling but went to voice mail. I left a message saying Mr. X, I wasn't able to take your call blah blah blah. I go back to write a follow-up email and realized their middle name is a female name. So then I'm like CRAP! They had a first name where it could go both ways and I just assumed it was Mr. X. Also in the follow-up email, I just said I tried calling you, please call back whenever convenient, and left them my number. I forgot to mention what time we should schedule the interview for next week because I'm stupid. I'm hoping none of these things will hurt my chances :(</p>

<p>What do you think?</p>
