According to multiple recent sources:
The selection process often begins with an online assessment that includes two major parts:
Cognitive + Technical Assessment — Aptitude, reasoning, verbal, plus some technical basics.
Coding Round (for technical/engineering roles) — 1-2 questions in a programming language.
There is also often a communication assessment or verbal round (especially for roles requiring client or business-interaction skills).
From sources:
Cognitive Ability: ~ 50 questions in ~ 50 minutes (English ability + critical reasoning + abstract reasoning)
Technical Assessment: ~ 40 questions in ~ 40 minutes (common applications, MS Office, pseudocode, fundamentals of networking/security/cloud)
Coding Round: ~ 2 questions, ~ 45 minutes (languages like C, C++, Java, Python)
In older/alternate pattern: A simpler format with Quantitative ≈15 Qs, Reasoning ≈20 Qs, Verbal ≈20 Qs all together in 60 minutes.
Quantitative Aptitude: Arithmetic (percentages, ratio/proportion, time & work, speed & distance), algebra, data interpretation etc.
Logical/Analytical Reasoning: Puzzles, series, coding-decoding, seating arrangements, blood relations, abstract reasoning.
Verbal/English Ability: Grammar (error spotting, sentence correction), reading comprehension, vocabulary, para jumbles.
Technical Fundamentals (for appropriate roles): Basics of programming logic, pseudocode, data structures/algorithms, MS Office, networking, security, cloud fundamentals.
Coding Round: For engineering/technical freshers; solving programming problems in Java, C++, Python etc.
Practice mock tests that replicate the timings and section-wise limits (e.g., 50 questions in 50 minutes, etc).
For aptitude & reasoning: focus on speed and accuracy—some sections are heavily time constrained.
For verbal/communication: good grammar + reading comprehension + vocabulary matter.
If you’re applying for a technical role: prepare programming basics, data structures/algorithms, pseudocode logic, and also understand fundamentals like networking/security/cloud as they may appear.
Do section-wise timed practice, since many sections may be individually timed or have restricted time blocks.
Pay attention to the most recent pattern (2025) because companies tweak patterns—one source notes changes such as removal of certain sections ("Analytical Reasoning no longer part") for 2025 drives.
