My compensation increased by at least $150,000 a year.
Best ROI I've gotten on anything I've done in my life.
I tell that stories to people considering doing it all the time, you'd be amazed how many people hear my experience and say, yeah, naw I'm not going to spend that time.
¯\_(ツ)_/¯
At the end of the day, it was the ~40-60 hours I put into Cracking the Code Interview that got me the FAANG job, the side project was barely a blip.
That's a weeks wage on what is essentially a lottery ticket, albeit with good odds. (Having done some freelance work for a friend in my Spare time, finding 40 hours free is going to take me weeks).
It really is a lottery ticket. Luck plays a ridiculously large part of the interview.
Half an hour later wandering done the street a very elegant solution came to me. I wouldn't say I am bad algorithmic stuff, but as I never practice it's pretty random whether I will get during an interview. "Luck" as you say.
What was your question bank.
