If you luck out and get a question that you wouldn't know the answer to were it not for the course, then I guess it helped.
I was thinking maybe if a recruiter is on the fence about reaching out, that might make a difference, but I'm pretty sure recruiters never read any LinkedIn profile and are 100% automated in all cases.
Understood from the poll above that it has very low to 0 impact in the final hiring decision. But how to get a call? For ex, if I'm a Mech or EE working on engg but not SWE, and have 10 yoe, how do I make recruiters call me for a screen in the first place? What are some tips to get that onsite if I have no "relevant" SWE experience? Again the goal is a 500K TC at FANG :-)
