The aptitude round consists of quantitative, technical questions mainly from java ,oops, ds concepts , some from os . Negative marking was there with 0.25 mark deduction.

It consists of three coding questions and that was pretty much easy . 1st qn is easy and so is the 2nd question . Third question is kind of medium level (but not so tough ) . It was a question related to doubly linked list . 1st and 2nd were array and string questions. We had this in pen and paper format , not in ids .

Numerical Reasoning: Numerical reasoning tests assess your ability to interpret and analyze numerical data. They often involve questions related to arithmetic, percentages, ratios, and data interpretation. Candidates may be required to perform calculations, analyze graphs or tables, and draw conclusions based on numerical information.

Verbal Reasoning: Verbal reasoning tests evaluate your ability to understand and analyze written information. They typically include questions on reading comprehension, vocabulary, grammar, and logical reasoning based on written passages or statements. Candidates may need to identify key information, draw inferences, and evaluate arguments presented in the text.

Logical Reasoning: Logical reasoning tests measure your ability to analyze patterns, relationships, and logical sequences. These tests may include questions on deductive reasoning, syllogisms, analogies, and pattern recognition. Candidates are often asked to identify the next item in a sequence, complete a series, or determine the validity of logical arguments.

Topics: Coding tests typically cover a range of programming topics, including:

Data Structures: Arrays, linked lists, stacks, queues, trees, graphs, hash tables, etc.
Algorithms: Sorting algorithms, searching algorithms, dynamic programming, recursion, graph algorithms, etc.
Problem-Solving: Candidates may be asked to solve algorithmic problems, implement specific algorithms, or write code to solve real-world problems.

The aptitude round had the topics of train and distance and time , OOPS , Core Java , JavaScript questions , Operating System questions and DBMS questions.
