A consultancy guy called me and processed my profile. They told me that they didn't have any JD about the vacancy.

After a week, I got an email from GS with a link to an online assessment:

1. Online Coding Assessment - 2 Questions
2. Telephonic Coding Interview - Whiteboard Interview (2 Questions)

Online Assessment

1. Forgot the exact question.
2. Given a string and a key, asked to encode and decode the string based on it.

Whiteboard Interview Questions (Most of the code and test cases will appear; you have to complete a method)

1. A robot can move in 4 directions: 'U' - UP, 'D' - DOWN, 'L' - LEFT, 'R' - RIGHT. Ignore all others. The position of the robot can be identified by array[x][y]. Please complete the method which returns the final position of the robot.

java private static Integer[][] findIndex(String testCase) { return new Integer[0][0]; }

Here, the test case contains characters like 'ULLLDDUU STRULR'.

1. A child is climbing stairs which has N number of steps. To add fun, the child can climb 1, 2, or 3 steps at a time. Find the number of ways the child can climb the N number of steps.
