Maze Sr Engineer interview questions

First I had a call where I was given very correct information about the position, in the technical interview the interviewer, although I completed the little challenge, told me that he was not going to continue with the interview since I had taken a long time having seen that I had to rewrite the code for a problem on the sandbox page. I wasted my time preparing for the interview, studying about the company, getting up very early to be able to fulfill my current job well (I am on a temporary contract) so if someone has time to spare, please consider going through this process of interviews.
