I am about facing coding challenge from one of FAANG. I did a couple of CS algo courses in a good university some years back. I just don't know the shortest path to prepare for this ?
2-3 problems a day (3-4 hours of study) has been the only approach that's sort of worked for me so far. Best of luck!
Just a fair word of warning. I don’t mean to discourage you, but you can’t expect to waltz in with no practice for these things.
I would hate for my previous comment to have discouraged you from even trying. If it's a simple online coding challenge, it might be pretty straightforward. It's the in-person round of interviews that you really need some solid prep for.
