Pebble Technology interview questions

Zoom call interview to go over what the job duties were and also I went over my past jobs and what type of experience I had, It was very smooth and fast process.

It was a hangout interview. He asked me to code on code edit. I was given a code and asked to write a solution in any language of my preference. I chose C. The crucial part here is when you encounter a 0 in a column for the first time, you make that column 0 as well as the row 0. But one consideration is we dont have to forget the 0s in the same column or row that might be there to make the corresponding rows/collumns 0s too.
