So, is SAS not used a lot in finance career?Many students in STAT recommends me to take SAS and they said it's very useful in finance.It totally depends on the company and position you do. For our program, we mostly learn/use C++, Python and R.
For quant industry:
-> if you are a Quantitative/High-Freq Trading Developer, you need to have strong CS background, and will have to know C++/C# or Java very well, especially scientific computing, high-performance, multi-threaded applications, etc. (I am not an expert in this field)
-> if you are a Desk Quant/Strat, you will very likely use C++/Python a lot. (Our program has high focus on this)
-> if you are a Trader / Portfolio Manager, you may use some VBA / Python / Matlab / R.
-> if you are a Data Scientist, you must be good at R/Python.
Some companies use Scala. SQL and KDB/Q are very common for database applications. As I said, it totally depends on the position and the company.
