For FAANG++ and Quant firms imo, it is worth learning via CLRS or other try hard book. I plan on reading thru it at some point. I got to Online assessment of my target company(quant firm which pays 200k+ ) just to get mogged by the questions they gave. I passed one but second one was some leetcode hard equivalent.
Unfortunately competition is extreme for the actual good paying companies and I approximate 400 leetcode(100 easy, 200 medium, 100 hard) is needed after your done with a solid foundation in DSA/language syntax. My long term goal in a year is to be able to do LC hards within 20-25 min, LC mediums in 15-20, LC easy in 10-15. As the standards have gotten really high nowadays.
