I applied both online and at the career fair. I only received a mock interview at the career fair. It has only been two weeks, so I don't know if I should wait longer.

During the mock interview, there were several classic questions, such as 'What was the biggest technical difficulty you ever met?' and 'Tell me something about you and technology.' Then there was one easy technical problem.

You were given an array of boolean values (it was a 2D array but packed into a 1D array) along with the width and height of the 2D array. Write a function that takes these as parameters, as well as a coordinate of a specific point in the 2D array, and then enables it.

I made some mistakes when trying to convert the x,y coordinates to the corresponding location of the same point in the 1D array. I was kind of nervous since this was my first interview in my life.
