It depends; I personally haven't used neural networks since graduating. Standard machine learning algorithms get used. I work with large data sets all the time.

It depends; I personally haven't used neural networks since graduating. Standard machine learning algorithms get used. I work with large data sets all the time. Sometimes correlations, regression things. The point is that 95% of the stuff that gets used on a day to day basis is not hard to learn. Especially if your background in linear algebra, probability and statistics is good. The five percent that delves into more complicated things can be figured out on the job.
