I understand every interview is different, but what happens if someone with 20+ years of experience fails a leetcode-type (say, LC hard or medium trivia problem) but aces system design?
My understanding is that you probably won't get the job
Then don’t play that game. Three of the 5 big tech companies (not including Netflix) have cloud divisions where they are hiring consultants - no LeetCode or algorithms required.
Yes. But the definition of fail is quite broad. My bitter experience shows that even simple syntactical errors (which are easy to make on a whiteboard especially if you are multilingual) were reason enough to throw me out.
