Here’s a structured guide to preparing for the Dilr CAT 2022 Slot 1 (Indian Technical Assessment Test), focusing on common question patterns, strategies, and sample solutions:
Dilr CAT 2022 Slot 1: Key Overview
Dilr CAT (Data Interpretation and Logical Reasoning) is a critical exam for tech roles in India, testing analytical, logical, and technical skills. Slot 1 typically includes:
Verbal Reasoning (Synonyms, Antonyms, Para Jumbles)
Data Interpretation (Tables, Graphs, Case Studies)
Technical Concepts (Algorithms, Databases, Networking)
Logical Puzzles (Seating Arrangements, Blood Relations, Coding-Decoding).
1. Verbal Reasoning & Reading Comprehension
Sample Question:
"Arrange the following sentences in the correct sequence:
A) The project timeline was approved.
B) After months of planning, the team finalized the budget.
C) However, unexpected delays pushed back the deadline.
D) The board rejected the initial proposal."*
Solution:
B (Planning → Budget Finalization)
A (Timeline Approved)
C (Delays Occurred)
D (Board Rejection Due to Delays)
Answer: B → A → C → D
Strategy:
Use the "First Step" method: Identify sentences with time markers (e.g., "after months of planning").
Look for contradictions (e.g., "however" in C).
2. Data Interpretation (Case Study)
Sample Question:
Given a bar graph showing sales of 4 products (A, B, C, D) over 4 quarters (Q1-Q4):

Question: Which product had the highest quarterly growth rate from Q1 to Q4?
Solution:
Calculate Growth Rate for each product:
(Final Q4 Sales / Q1 Sales) - 1
Product A: (240/150) - 1 = 60%
Product B: (180/120) - 1 = 50%
Product C: (300/200) - 1 = 50%
Product D: (250/100) - 1 = 150%

Answer: Product D
Strategy:
Focus on percentage change, not absolute values.
Use prefix sums for cumulative data questions.
3. Technical Concepts (Algorithms)
Sample Question:
What is the time complexity of the following code snippet?
for i in range(n):
for j in range(n):
if i > j:
print(i)
Solution:
Nested loops: O(n²)
Condition Check: Reduces inner loops by ~½, but still O(n²).
Answer: O(n²)
Key Formulas to Remember:
Binary Search: O(log n)
Merge Sort: O(n log n)
DFS/BFS: O(V + E)
4. Logical Puzzles (Seating Arrangement)
Sample Question:
8 people (A-P) are seated around a circular table. Each person likes a different fruit (Apple, Banana, Cherry, etc.).
Clues:
A sits between B and C.
D likes Banana and is opposite to E.
F is next to G and H.
Solution:
Circular Arrangement: Fix A’s position.
Clue 1: B and C are adjacent to A.
Clue 2: D (Banana) and E are opposite.
Clue 3: F-G-H form a trio.
Answer: Draw a diagram and validate constraints.
5. Exam Strategy
Time Management:
Allocate 15 mins for DI, 10 mins for Verbal, 20 mins for Technical, and 15 mins for Puzzles.
Technical Section:
Prioritize arrays, strings, and sorting (common in Dilr CAT).
Practice Resources:
Mock Tests: Use platforms like GeeksforGeeks, Testbook, or Cracku.
Previous Year Papers: Analyze patterns (e.g., 2021 Slot 1 had 3 DI sets).
Final Tips
Mock Tests: Simulate exam conditions to improve speed.
Technical刷题: Focus on LeetCode Easy/Medium for coding questions.
Verbal Speed: Practice synonyms/antonyms using Word Power Made Easy.
