I had filled out the online application on Tuesday, March 1st, and received an email the next day asking me to do the video interview! I only submitted my resume, and not a cover letter, but I was still invited for the Hirevue interview.
I completed it on Saturday, March 5th. They asked me six questions, all of which I found here on this website! I went through all of the interviews listed on this website and wrote down potential answers for them, so when I did the video interview I was ready to go. I had my word document open beside the Hirevue website, so it was really easy.
The actual interview was kind of (really) nerve-wracking, but they gave you practice questions to get a feel for the website. And you can do it as many times as you need. It's been five days and I'm really anxious to hear back. Once I do, I'll come back and edit this if I get a face-to-face.
*I DID NOT GET THE OFFER YET*
Also, if you're applying through the United website, I was having trouble with the Taleo program; I tried saving my application as a draft to return to it later, but it kept deleting my information. So, if you're using the same program, I would recommend doing it all in one go!
Also, I posted my answers to the questions as sort of a guide for those reading, I worked really hard on them, so use them as a guide, but I really recommend creating your own answers. Please don't copy mine; let your personality shine!
