There are three types of card shuffling preparation used.
One is basically old school and has been mostly phased out, except for possibly in some higher limit exclusive properties and of course only on Macau style baccarat tables. Which is unwrapping all eight decks of brand new factory sealed/wrapped decks of cards. Discarding all jokers and the brand name 'ad' card. Exposing them all face up and then piling them together, placing to the side. Repeat for remaining 7 decks. Wash all face down on the table extremely well. Group back up into approximately one or two deck piles. Manually shuffle. Place against empty shoe and make straight. Cut and burn as they still do. NOTE: At the end of the shoe if using this procedure, they would put the used and handled/mangled cards into a large zip lock style secured bag, write the table and game number on a label and two personnel would sign the bag.
Another one is the machine shuffler that has two, eight deck shoes going for rotation. Used both on Mini and Midi/Macau style baccarat. Of course when it is Midi/Macau style, the shoe put into play would be immediately replaced with a new shoe to be shuffled while the current one is in play.
Finally, we have the pre-shuffled deck arriving at the table in a clear and ID'd lock box. These boxes come from an approved and legally compliant vendor that must adhere to state gaming rules and regulations, while being subjected to civil and criminal penalties for wrongdoings including collusion.
NOTE: I have witnessed some properties that 'mini shuffle' a machine shuffled shoe of cards coming out for play or a pre-shuffled vendor lock box. A 'mini shuffle' is where the dealer will roughly breakdown the shoe of cards into approximately 6 or 8 piles and do a real quick manual shuffle without a wash.
I have played them all for many many years. They were all included everywhere I played, in excess of 50 B&M casino properties.
One thing they all include at everywhere I have played hands down, is that once the shoe is ready for play the red/yellow cut card or some other color card is giving to a player to cut the shoe and then the shoe is cut and then the sections are repositioned front to back. Also the first card is turned face up and the corresponding appropriate amount of cards are removed from the front of the shoe and burned.
With the unknown moving of the front to the back of a variable sized section of cards, as well as a variable amount of burned cards, there is no way it can stand as if the shoe was shuffled or set in any way, shape or form. None whatsoever.
Yes that is a strong statement I am giving, but if you sincerely think about it you will realize it is such fallacy that is perpetrated on many of the forums accusing casinos of pre-setting shoes to trick or fool players, etc. Or even alter the house advantages.
I have taken an extensive amount of time a few years ago and bought dozens of shoes of cards and sorted out several eight deck shoes myself. I set up all kinds of events in series, in groups, in sections, within the shoes as well as setting up entire shoes. Like I said, I invested extensive time spent doing countless set ups of the decks and shoes. Always comprising multiple decks within the shoe or nearly the entire shoe. I did a random cut and burn the appropriate amount of cards. Never did any sizable amounts of my set ups ever remain within those shoes when I played them out.
If it matters and for sense of definition, I set up the following. Series of chop-chops, 1s and 2s, doubles, weak then clumping/strong, long streaks, etc., etc. All kinds of scenarios in all kinds of orders and lengths. Nothing held true. As well, I set up varying lengths and sections of basically nothing and confusing mini patterns without substantial definable anything. Those as well change significantly also.
If you don't believe me, invest in 16 decks or even 32 decks of cards and set up 2, 3 or 4 shoes and spend hundreds of hours or so in your own research. Simple! Set up the shoes anyway you wish with or without patterns and trends, with non-beatable scenarios, etc. Write it all down each and every hand what is supposed to happen. Write down what actually happened. Do it over and over and over. You should come to the same conclusions I did. Once that deck is cut and repositioned and anywhere from 2 to 11 cards are removed, it totally changes everything with any possible set up of that shoe of cards.
Easy to perpetuate rumors and fallacies on the forums I agree. Don't be lazy, do your own research.
Here is the New Jersey Admin Codd reference pre shuffling and vendor pre shuffled cards. Other states all have similar civil and criminal admin gaming codes that casinos must follow. Those of you that think there is a secret room where casino personnel are setting up shoes of pre shuffled cards, some with choppy, some with streaks, others with strange and unfollowable patterns/trends, better rethink your fallacy thinking.

Notes
N.J. Admin. Code § 13:69E-1.18A
Besides from casinos pre-shuffling their own shoes, they can also purchase pre-shuffled vendor supplied shoes of cards and place within their own clear shoes to transport to the table for play.
Here is what the offered product looks like from one vendor.
