I applied via Campus Placement and was interviewed in Dec 2024. There were 5 interview rounds.
The assessment focused on general aptitude, which was relatively easy and manageable to pass. However, the pseudo-code section may pose a greater challenge during the first round.
It is very easy; you just need to speak at least once to easily pass through this round. mostly they dont try to reject you unless you are very nervous and very low about confidence they want you to speak atleast once , even the point is valid or not.
You will undergo a written test comprising three coding sections (either in Python or C) containing five or six questions each, along with ten multiple-choice questions on software testing, which are relatively easy. However, the most challenging section is networking, for which you will need to write theory responses; therefore, it is important to prepare thoroughly for that part.

HCLTech interview questions for popular designations
I was interviewed in Dec 2024.
20 - MCQ test related C&C++ basic to advance
2 - coding questions -
1) create class which allows only one instance creation at a time if you try to create another before deleting existing object then class should throw exception..
2) find the distance between leftmost string and rightmost string(string's chars order doesn't matter) In a given long shuffled string.
Ex :-
Shuffled string = "xaxxcxbxxxcxxaxxbx"
target string= "abc"
Ans: 3
(Leftmost string is last index 6
Right most is 9 so 9-6=3)
Note:- other chars not necessarily 'x' it can be any
OOP is a programming paradigm based on the concept of objects, which can contain data and code to manipulate that data.
OOP focuses on creating objects that interact with each other to solve complex problems.

Polymorphism: Objects can take on different forms or have multiple...
Runtime polymorphism allows objects of different classes to be treated as objects of a common superclass.
Use virtual functions in base class and override them in derived classes
Use pointers or references of base class to call derived class methods
Example: Animal class with virtual function 'makeSound', Dog and Cat classes overriding 'makeSound'
STL libraries provide efficient and easy-to-use container classes like Vector for storing and manipulating data.
STL Vector is a dynamic array that can resize itself automatically.
