Data Structures & Algorithms (DSA): Focus heavily on Linked Lists and Arrays. Common coding problems include:
Reversing a singly linked list.
Merging two sorted linked lists.
Sorting subarrays or finding unique elements.
Differences between linear structures (lists) and hierarchical structures (trees).
Object-Oriented Programming (OOPs): Be ready to explain and provide examples of Encapsulation, Inheritance, Polymorphism, and Abstraction in Java or Python.
Databases: Refresh your knowledge of SQL Joins (Inner, Outer, Left, Right) and compare them with subqueries

It was very easy. They asked basic concepts in the technical interview and a few easy questions to solve. It included aptitude questions aswell. They also test you about data structures.
I applied online. The process took 3 months. I interviewed at Cognizant
Interview
First they asked for my Introduction after that the interviewer started asking Technical Questions and followed by few Logical Questions and later asked me if I have any questions snd the interview was done
