The Lactation Network interview questions

I was excited for this interview as I love what they do. However, I was getting over a cold (my voice was definitely deeper in the interview) but I dressed my best and answered all of the interviewer's questions well. We had a good conversation too but I was sent a rejection a couple days later. No feedback. I thought to myself, was it because I was sick? Rescheduling the interview would have looked bad on my part. I'll never know but it bummed me out.
