I can share my reviews based on my last 2 months experience on InterviewBit which helped me landed a job in Amazon :).
A super interacting platform which intelligently allows us to customize our preparation schedule based on our time bandwidth. A simple and beautiful interface which gives me feeling as if I am being coached by real instructor. On top of that when I used to get reminder mail everyday from InterviewBit about not losing my streak was so compelling that even after doing 10 hours of office work I was able to code for next 1–2 hours.
At one point I got so addicted with this platform that while sleeping I used to think what test case might be failing and sometimes it came in my mind and immediately I used to open my lappy and submit the new code and woooohhhaaa after seeing those 3 green ticks what a sleep I used to get.
My preparation through this platform:
Set the threshold to minimum 200 points but I always fought for 500 points/ day but sometimes with regular job it is hard to maintain 500 so kept it 200.
I started with Complexities and then worked parallel on Tree and Arrays. Then Binary Search and linked list and so on. My objective is to work on two different modules at once because 1. I wanted to keep my preparation in Jet mode, 2. Sometimes when I was unable to submit a tree code then rather than taking rest I used to jump to array and started working on array problem to get me out of the jinx of tree question.
InterviewBit allows us to start new session and I was using this feature to revise the module and to speed up the coding in second round. My goal in first round to submit the correct code irrespective of time and in second round my goal was to submit the correct code in minimum number of attempts and in at least 0.75 time efficiency compare to average time mentioned against each problem.
In a matter of 2 months I was able to complete the course with revision and finally got offer from Amazon India and Visa Inc India in my first attempts only. Thanks a lot team InterviewBit. :)
