Google recruiter has contacted me for a software engineer role since i have been actively applying to the roles in google.
Intially the interviewer introduced himself. Later i intrdouced myself.Similar to "Tell me about urself".
A shared doc was sent to me with the interview mail.

He has given me a question similar to https://leetcode.com/problems/the-maze/.
But instead of ball it was car, and the walls were denoted by '#' and empty space denoted by '.'
I tried to explain my understanding of the question and later how would I like to approch. He gave me hints for optimazation.
But i was struggling a bit to code.

He thought to make easy for me and gave an another one.
Gave a RXC matrix.
Find 3x3 matrix whixh requires the least amount of water.
I started to code, discusing the approch. He asked for few of the edge case to cover.
I haven't code completly, he just asked me to break the function and solve sub function where it takes indexes of a crop in the matrix and returns the sum of it.

Don't know the result yet. But i guess my performance was not great. And it is google obvious i have to do better.
But i thought this interview will give experience and it is a learning.
It was a good experience talking to the professionals in google.
Would definetly give try again with better preparation.
What helped me progress/ made easy for the interviewer is instead of only discussing, you also need to give some pseudo code so that interviewer could able to interact with you more.

Please do share if any resource / plan helped you progress in coding.What approch helped you identify what concept to use for a particular question?
Thank you!!
All the best for ur interviews.
