The right way to hire is not four rounds of data structures and algorithms but work like the job, plus asking a candidate why they made each choice.

I'm not going to spend four interviews going through and asking somebody data structures and algorithm stuff. I just have them do work that might be similar to something I'd give them on the job or even just have a conversation with them. See how they think. Like can they think through trade-offs? I don't even care about what answer they give me to a problem. I care about like what's like why did they say that?
