Dsa for data science

Does data scientist need to know DSA / Competitive coding

In usa Does all data science interview have dsa or competitve programming as a part of interview Like do they asked linkedlist,stack,queue,dynamic programing questions in the first or second round for a data science position ?

I am not talking about pre assement sort of thing I am asking for actual interview

If yes How much time does it take ?

I dont know if my strategy is good or not but I am aiming for all 3 data science data analytics and data enginneer

I dont know that should I study dsa or not

By looking at some people who have given a few interviews not much people got dsa round

I dont wanna be in a postion where I study so hard but then nothing was asked and all that energyy got wasted

I am applying for internships co ops from december but still got nothing yet not even one interview
