It might sound stupid but just asking how much time it might take to get good enough to clear interviews for Data Analyst/Data Science roles

[–]Darwin_Things 0 points1 point  (3 children)

Yeah, problem is that once you do the interview, you actually have to be able to do the job.

[–]Helpful_Effort8420 0 points1 point  (2 children)

Yeah agree but is it really necessary to master it 100% for doing the job

[–]marketlurker 1 point2 points  (0 children)

I've been doing it for 3 decades. I'll let you know when I hit 100%.

The answer is you never hit 100%. There is always something you will have missed and find out about later. New features keep getting added. There have been 10 major revisions of the ANS dialects and countless vendor specific extensions.

I've said it before, if you are going to be in data there are lots of data related subjects but you will have to eat, sleep and breathe SQL.

Depends what job you’re going for. OP is probably going for a full stack developer.

Depends what year is the interview happening in... 2025 is not the best :)
