Applied: mid October
OA1: ~ end October
OA2: ~ mid Novermber
Onsite: early December
Feedback: 3-5 days after onsite

Whole process: October -> December

I applied online without referrals, and got a techincal OA within 4 days, second OA (behavioral) 3 weeks later, onsite scheduling 2-3 weeks later.

The questions focused mainly on trees and arrays.

Onsite Qs:
Find maximum average subtree
Array maniupulation (I forgot which exactly)

Note, for Q3, you need to find all possible combinations, a word can be broken up into n+ times.

In my opinion, the hardest part of this process was definitely the behavioral questions (OA2, aka work stimulation). Good luck!
