Question on a plant

[Nikkm]

Hi. I'm taking care of this plant for my boss during the pandemic. Long story short: it wasn't watered regularly prior and doesn't have a drainage hole in the pot and inadvertently got over watered to the point it was sitting in mud. I immediately changed the dirt.
My two questions are: what type of plant is this and do you think it's salvageable (and if so how?).

Oh dear .......Welcome to the forum @Nikkm At the moment it`s just a teeny bit difficult to identify - although I will have a think about it. All you can do immediately is wait. Keep an eye on it and report back in a couple of days.
Can we assume you now have it in a different pot with drainage holes? If not, that would be the first move, and just dampen the new compost a bit too.

Did it used to look anything like this Dracaena?

This is a form of Florist's Croton known as Gold Dust Croton (Codiaeum variegatum 'Gold Dust', or similar cultivar).
