Bit manipulation - is it worth learning for interviews?

I've been avoiding bit manipulation because it feels like a niche topic. But I keep seeing it pop up in Google and Amazon interviews.

Questions I've seen:

Single number (XOR trick)
Counting bits
Power of 2
Reverse bits

Are these common enough to warrant dedicated study time? Or should I focus on more frequently asked topics like trees and DP?

Also, any good resources for understanding bit manipulation intuitively?

I think bit manipulation is definitely worth learning, especially if you're targeting big tech companies. It's not just about solving specific "bit" questions, but understanding bits can also help optimize algorithms. For resources, have you checked out the "Bit Manipulation for Beginners" series on YouTube? Super helpful!
