Infosys Digital Engineer Specialist interview questions

Made me wait 4 hours before starting. The interview was a two-parter, a technical round followed by and 1-1 interview. My interview was cut short because I failed my technical round very badly :/

It was a simple interview, first was a technical round in which I was asked two questions and was asked to solve one in 30 minutes. The questions were Higher Medium - Lower Hard level(Leetcode). One of the questions was on a binary tree and another was on a type of sum maximisation in array. I failed to solve both and the interview was short, just basic questions about myself and low-level algorithms.
