If by inventory Tetris you mean something like RE4’s attaché case system, then no there’s no reorganizing like that - it’s closer to the Witcher 3’s system, with a big grid of square images for each item and a section to the left depicting the character and where equipment can be slotted in. It’s all just a bit cumbersome - item images are small and sometimes fairly generic, sorting options are few, juggling which characters are holding what, characters’ inventories that are back at camp can’t be accessed unless you go back and switch them into your party (AFAIK), which involves telling one character to stay behind, confirming with them, going over to the new character, asking them to join, THEN accessing their inventory.
