I would love to hear more about why this is if you're willing and able to share.
Having gone through this last year, I figured I can offer a little bit of help here. This could be out of date because it's from Season 50, and casting agencies etc change all the time.
I don't recall the order last year honestly, if a casting agency that does Game Shows contacted me or if I applied on the website first. One led to the other though. I feel like an agency contacted me and direct me to apply but I may be misremembering. As a huge fan of the show, I was excited but I didn't think much would come of it. This was maybe in June 2021.
I got a text from a casting person from the Price is Right asking to set-up a call on July 1st or therabouts. That call led to more information and maybe was when I actually applied on the site. I set up a zoom audition with another producer for about a week later.
Most of the information in this e-mail was about what to wear, how to set up the camera/laptop etc correctly with good lighting, about standing and having lots of energy, dressing business casual. It also asked to make sure you familiarized yourself with the show, and knew what your favorite game is (and specifically said don't say Plinko). It strongly asked for recommendations of any friends and family that would be good on the show so they could do their own zoom interview.
The next week I did the zoom call. The producer made me move the camera a bit and turn off some extra lighting to get the right look. He was constantly on the zoom call clapping and swinging his arms trying to get more energy. He made me come on down, and then made me do it again with some coaching. I'm assuming this casting agency was cutting these zoom interviews down and passing them to CBS, dunno. Seemed like it went well.
A few weeks later I got a text that said they liked my tape but were waiting to hear from the Network (maybe?) but wanted any other friends or family who would be good on the show, esp Police or Firefighters.
4 days later I was texted again, with the show asking if I was fully vaccinated for COVID and also for availability in August/Sept
A week or two later I got a text on Friday, inviting me to tape on Tuesday. I had to bring at least one friend or family member, we both had to be at the studio on Sunday for COVID Testing and upload vaccine cards. Any friends or family you brought were eligible to be called down if they liked them. I accepted even though I knew it'd be tough to find someone that short notice (and childcare for my 4 month old so my wife didn't get to come with) and that evening a producer called with more info on all the specifics and sent a long text with info. The most interesting aspect was that if you were not selected in Show 1, you could change shirts and stay for Show 2 (and presumably 3) with another chance to be called down. I think you all deduced this last season seeing some people in the audience for multiple shows.
From there it was a pretty normal Price is Right taping experience. Arrived outside the gate, got let in. Phones were taken immediately though (not after the interview). IDs and maybe Covid cards were checked again. Paperwork signed and name tags made. IDs ran by producer and photos taken. Down the side of the building and waiting for group interviews with casting producer much like Stan did.
Groups of 3-4 contestants and their guests doing interviews with casting producer and an assistant taking notes much like Stan. Masks off for interview only. Imagine if everyone got a "good" Stan interview. It did seem like more time was paid to the people who applied and were "cast" vs their guests. Hard for me to say though. I made a good joke about my favorite game but right now I was playing "Secret X" with the assistant's sheet and trying to get one next to my name. This seemed like a final check to make sure the people they liked came across great in person one last time.
Moved on to the area with show playing and bathrooms. Loaded into studio and seated in pods. Masks, purses, bags, jackets all hiding behind the pods (besides the phones being taken, no other lockers or items held). None of us had seen the stage, pods or Alexis yet so a lot new considering 50 hadn't premiered (and I think we taped before the premiere week even).
That was pretty much it, I think those who stayed for another taping went back and rejoined the next show's line, did another interview etc, but I was called down in Show 1 so I didn't stay.
