Got messaged by a C3 . ai recruiter. Read that wlb is bad and that the interview process is absurdly long, but the Glassdoor reviews are 4.2 and can't find actual hours worked posted by anyone. How's the culture really? I'd be aiming for DS consulting, something more functional but with DS/ML concepts as my differentiator.

10, but only because I am in a part time masters. But I never use it professionally. 95% of “DS consulting is more like a solution architect role or project management for data migrations. Not a lot of core DS work in consulting.
5/10 R, 7/10 Scala, 8/10 PySpark, 10/10 SparkSQL or SQL. I think others have covered how rare it is to actually get to do it for a client. Any time coding comes up is when my job touches task estimation, use case to story translation, and translating from DE to business or DS to business...

Give up R. Not used in industry outside of academics or academic adjacent professions (PhD level high finance like quants / derivatives) or government think tanks. Literally no one has used r in 7 years career except for 1 guy, who was an ex quant
Use the swirl package, it's kind of a cool concept built to teach you R using R. I also liked datacamp for some specifics. Finally, vignettes and googling. Learn by doing.
I wouldn't bother with books, though stats books with R examples can be useful if you want both at once.
I'm not a data scientist per se, but I work in a very data-heavy role within consulting. Maybe it's just my projects, but a lot of need for "data science" is really just ETLing large csv files from what I've seen. Just knowing Pandas and Numpy and knowing the basics of Python will make you a god compared to 90% of the people I know that would crap their pants if the firm stopped buying Alteryx licenses.

More than likely, you will need to do a case interview and 70% chance it’s not data related.
Google “crafting cases” and watch their videos. Start practicing ASAP. Casing is hard if you’ve never done it before
Pandas, scikit learn, numpy, sql

Lol RARELY
I've worked in defense/natsec consulting, and R was either not an option or an alternative to Python. So it was never necessary. For gov consulting I recommend focusing on python
