CTCI or LeetCode?
I'm currently working through the book Cracking the Coding Interview. Should I focus on the exercises in the book and then back to LeetCode? Or do both at the same time?
I would suggest to finish first 3 chapters from CTCI and start solving array, string, LinkedList, stack and queue questions on leetcode. Once you are comfortable, you can do in parallel.
Both will work, so do the one you can stick with more consistently. I find LC a lot more enjoyable.
CtCI then LC for company specific questions before the interview
Yeh I keep reading about the importance of Big O notation but struggle to get my head around it and remember it, so trying to get the first few chapters done and focus more on LeetCode
Donât spend much time in initial chapters. And donât remember anything. Try to calculate it. Donât go for EPI right away, thatâs what I can suggest. EPI, you can start after CTCI
I struggle with the calculations. Is EPI a book?
EPI (Elements of programming interviews)
Those who work at Amazon, how hard was the interview? I spoke with a recruiter and he gave me a lot of stuff to work through before I apply but don't feel like I'll ever be ready
Leetcode easy / medium with an occasional hard thrown in
CTCI first. Read only the chapters on data structures and algorithms. Then leetcode.
