How to Prepare for RA/TA positions

[Sally_j]

Hi

I got into UC Berkeley Master's program and am looking for RA/TA positions. I also got into Boston University. An alum from BU recommended me to prepare for data positions from this resource ( dataanalyst.xyz ) because data jobs are abundant across departments. I also inquired with Berkeley admissions advisor and she told me that there are many data related positions. But I am not sure if this is a good enough resource to prep for positions at top schools like Berkeley.

Can someone who is familiar with data roles give me some idea or share some resources?  Thx!
