I got a call from recrutier through LinkedIn. Then she asked me to complete OA in 3 days. In OA there are 2 questions and i submitted the code with all test case passed.
Also OA has many more leadership and design related questions.it was for around 2:30 hours.
After 5 days i received a call from HR ..and she shared the positive result and then asked me to prepare DS , Algo, HLD, LLD and leadership principles. I took 2 weeks of time to prepare.(In that time i finished the followings.
- 14days study plan to crack Algo
- 2 week study plan to tacke DS
- Ultimate DP study plan
HLD from codekarle.com
LLD (BookMyshow, Hotel booking, parkingLot, and OOPs cocepts in details(design patterns), etc)
Round1:
20 minutes of leadership principle questions
HLD : to create a system where multiple users can register in to it where each can follow each other;(like twitter)
one can do following actions...i.e. upvote/downvote a product, give comments to a product, give review to a product, n all.
if a user do sny such activity from above , that should reflect in his profile.
similar to twitter.
Round 2:
20 minutes of leadership principle questions
1. Given a sorted array, where every element except one element is repeated. find out that non repeated number.
2. median of a contineous stream
Round 3:
20 minutes of leadership principle questions
LLD: Design a service which will accept a bimary matrix and provide the number of island available in that matrix.
I have ansewerd all the questions especially DS and algo without any error. HLD and LLD discussion also i am satisfied. Waiting for the result.
Any idea of the further rounds and what to be prepare if i get a call.?
