Really this is more of a question of what domain you work in.

Since most algorithms apply to very specific data and needs of that data to do something.

Yes, it's a deliberately open ended question to get a feel for which algos people are using for which problems.

An experimental algo similar to Word2Vec

Another experimental algo which compares rich vectors for similarity which is a variant of an uncentered Pearson Correlation

None.

I haven't implemented a single computer science-style algorithm since I graduated. Even the rare times I need one there are perfect (i.e. bug free/edge case free) pre-existing examples available.

This is likely true for the silent majority who are doing CRUD or web development.

Binary search- to find the file that causing the build to break .

Barrier pattern to deal with threads, although I mostly can let libraries deal with that.

Those are two I can remember using recently. I once worked on a very big graph search problem using A* and some other algorithms. That was fun.

Dichotomy search is still by far my most used algorithm. Say you want to figure out why a regression happened between commit 1 and 100, please don't build all versions in sequence :-)
