I attended only one round of an interview and walked out of Deloitte. The interviewer was an irresponsible person. He talked on the phone for more than 10 minutes during the interview. He was yawning every 5 minutes. He gave some unclear questions and was expecting different things. Refer to the below silly and stupid questions.

You know JavaScript, right?

What is var?

What is $?

var a = 10?

Input: 1 2 3 3 5 Output: 1 2 3 4 5

Use any data structure to get the output.

WTF, that means: is it replacing the second 3 by 4, or replacing index 3 by 4? No clear instructions.

If asked, he started writing a loop to iterate.

And the expected answer was ConcurrentModificationException. I think he has to learn: with a for loop, there is no such exception that happens, and if we do it using an iterator, the exception occurs.

3 2 1 3 2

Get the second minimum using SQL?

How to declare a class as a Spring Controller using XML?

Difference between null & undefined in JS?

How to get an int from "123" in JS?

Difference between PreparedStatement and CallableStatement?

var r = 1 + "1"; and var r = "1" + 1;

Write output.
