I was talking with HR and then had a technical discussion. I am talking with to person. I got manual questions and questions with Java. I talked for 1 hour. Ask about integration tests, and create bugs. Ask about string. Find the number of unique characters in a string. If you find the word "Visa", print "Visa" otherwise print "Visa not found"Ask what a is hashmap. I wrote algorithms. public class FindwordinString2 { public static void main(String[] args){ String str = "This is ,Inc office"; String find = "Visa"; boolean val = str.contains(find); if(value) System.out.println(find); else System. out.println("Visa not found"); } }
