Given how painful transcribing audio is, people repeatedly ask us why there is still no software that can automatically take an audio and spit out its transcribed text with good accuracy. Now, it’s not entirely true that there is no such software - there are many, but they don’t help in transcribing real-world audio which typically involves handling multiple voices and all kinds of background noises.
Training a machine to recognize human voice has proven to be very difficult due to the variations in how people speak a particular language. Despite being the most widely spoken language, English itself sounds considerably different in various parts of the world.

Based upon what I've read, and my experience, it takes a minimum of 4-5 hours to transcribe 1 hour of digitally recorded interviews. Now the real question is, what's your time worth?

It is natural to be anxious and nervous for a job interview. My advice is set aside ten-15 minutes right before the interview time to do something that relaxes you and takes the edge off. Yoga, meditation, reading, a brisk walk, a calming drink ( nothing with caffeine, alcohol, or an energy drink), a quick snack. Go into the interview relaxed as you can be.
