How to print even & odd numbers concurrently using thread? How to use Optional Parameter? If you have two generics defined of type string, int in main method, but you have to run only string one.How you will do so ? What is the difference between hiding method & overriding method? They said to write the code. Write a code to make a list of object type? They will give some test scenarios to write test cases. Some Automation basics. Some Sql queries like find the second highest salary from employee table.

I'll focus on the technical part of the interview only. This consisted of creating an automated test solution within 5-7 days, The AUT is the production app itself. This is a bit tricky, because there are measures in place to detect fraud and automated scripts, which are usually bypassed in test environments. As I understood it this part will somewhat change in the future, because it's not 100% fair. Afterwards there was a technical discussion, which was a bit easy, but on point. There was no nonsense like reciting documentation from memory, that you encounter in other lame interviews at other companies.

Solve either one the below coding question you have to move zeros either to end of the array or bring them to beginning of the array. For example, if {14, 0, 5, 2, 0, 3, 0} is the given array, then moving zeros to end of the array will result {14, 5, 2, 3, 0, 0, 0} and bringing zeros to front will result {0, 0, 0, 14, 5, 2, 3}. Solve without using For loop and without using a new blank array/collection. Write a Java program to replace all leading and trailing zeroes in a number without using Replace function. Eg. input - 0001120380.0000 output - 1120380, input - 00012.001200 output - 12.0012
