Super cool interview

Nice

What was he answering?

It's really true that number of experience is inversely proportional to the coding efficiency.

Thanks for sharing live interview.. It was worth watching.. I am working on similar tech stack close to 6 yrs exp in java backend and looking for new opportunities.. let me know if still there are any openings.. awaiting for more similar videos..

For the algo question answer , i don't remember if the panelists asked NOT TO USE any inbuilt methods. If they said so then pardon i am sorry. In that Case ONLY ONE LINE CODE WILL DO:- int ar[]={0,0,1,1,0,1,1,0,0,0,0,1,0,0}; Arrays.sort(ar); for(int i=0;i

Sir thanks for sharing the interview experience it will help us a lot

Rejected

Ashwin was already impressed and decided him to select 👍🎈

For those looking for answers of the Algo question. Its simple in-place algo (You can say its a simple swapping the numbers algo). int[] intArr = {0,1,0,1,0,0,1,0,1,0}; int j = 0; for(int i =0; i 0){ int temp = intArr[j]; intArr[j] = intArr[i]; intArr[i] = temp; j++; } }

Hi sir, if there are any openings. please let me know

Coding knowledge is very poor

Bro does any coupons working to get databricks course? Please let me know

I would reject this candidate as per his this interview.

Is he got selected?
