Infosys Programmer Specialist interview questions

2 interview rounds were held. First interview round was very easy with basic DSA questions of 1d array. Second round was bit difficulat for me as it was only related to java and its basics. Like what was introduced in java 8, what was introduced in java 11, what was introduced in java 17. Do you know Lambdas, Furture, Promise in java, etc.
