Platform is Awesome, I gave it a go and recorded an interview with the coach where you can preview their voice. Conducted a practice interview with the coach helped me to gain confidence, i would say it is a preparation tool what to expect in a real life scenario. Some people may be great at interviews i am not that great, for me it will will help me as long i have knowledge on the questions asked.
When you practice for your interview for the first time, you have the option to select the interviewer, can preview their voice before continuing, select the feedback intensity, focus clarity, couple of options to choose from i chose clarity. There are also few interview types i went for mock interview, duration of the difficulty level, i chose easy and can select the duration of the time, then hit start interview. How you communicate with the Interview Coach will score you based on filler words which you will need to avoid and how you respond to questions, this can be found on the left hand side.
Have fun guys, keep practicing
