Persistent Systems Fresher Software Engineer interview questions

I was asked to introduce myself and questions from my resume (oop in python etc). The next question was given 4 numbers as input find the maximum time that can be formed. Ex: 1,2,3,4 output: 23:41. I was asked to code in language of my choice and they wanted to check how I code. I couldn't answer that and I was told the interview has ended.
