It was early morning. We had everything in MCQs from aptitude to coding to core subjects. Everything they asked were jn mcq form.
The time was pretty much okay since MCQs were designed in a way so that we don't have to calculate much and also every section was timed separately. So once time for a specific section ends you can't answer them later.

Asked in companies
You are given a Singly Linked List of integers. You have to return true if the linked list is palindrome, else return false.
A Linked List is a palindrome if it reads the same from left to right and from right to left.
Example:
The lists (1 -> 2 -> 1), (3 -> 4 -> 4-> 3), and (1) are palindromes, while the lists (1 -> 2 -> 3) and (3 -> 4) are not.
Problem approach
I gave O(n) both time and space solution using stacks but interviewer asked to optimize it and give clue as well.
I understood the clue and was able to optimise the code. I was not asked to code in this round just had an discussion but few of my peers were asked to write code as well.
2. OOPS Question
They focus a lot on OOPs and Java. I was grilled well from four pillars to advanced topics in oops.
1) Four Pillars
2) Keywords
3) Access specifier
4) JVM & JDK
Problem approach
Tip 1 : Prepare oops well
Tip 2 : Have solid foundation in Java.
