Meta vs Infosys: Interview Question Comparison

When preparing for technical interviews, understanding the specific focus and expectations of each company is crucial. Meta and Infosys represent two distinct ends of the tech interview spectrum: one is a top-tier FAANG company known for deeply algorithmic assessments, while the other is a global IT services leader with a more applied, problem-solving approach. This comparison breaks down their question banks by volume, difficulty, and topic focus to guide your study strategy.

Question Volume and Difficulty

The sheer volume of available practice questions is the first major differentiator. Meta's question bank is extensive, with 1,387 questions categorized by difficulty: 414 Easy, 762 Medium, and 211 Hard. This large pool reflects the breadth and depth expected in their interviews, which are designed to rigorously test data structures, algorithms, and system design fundamentals. You must be comfortable with a high proportion of Medium and Hard problems.

In contrast, Infosys has a significantly smaller bank of 158 questions: 42 Easy, 82 Medium, and 34 Hard. The lower total volume suggests a more focused or curated set of problems. While the difficulty distribution still leans toward Medium, the overall ceiling is likely lower than Meta's. Preparation here involves mastering a core set of patterns rather than tackling a vast array of complex algorithmic challenges.

Topic Overlap

Analyzing the top topics reveals both common ground and key distinctions.

Shared Core Topics: Both companies emphasize Array and String manipulation, as these are foundational to most coding problems. Math-based questions also appear in both lists, covering basics like number properties or simple arithmetic logic.

Meta's Distinct Focus: Meta highlights Hash Table as a top topic. This underscores the importance of mastering efficient lookups and leveraging hash maps to optimize solutions from O(n²) to O(n) time complexity, a common interview optimization step.

# Example: Two Sum using Hash Table (common Meta pattern)
def two_sum(nums, target):
    seen = {}
    for i, num in enumerate(nums):
        complement = target - num
        if complement in seen:
            return [seen[complement], i]
        seen[num] = i
    return []

Infosys's Distinct Focus: Infosys lists Dynamic Programming (DP) as a top topic. This indicates a strong emphasis on problem-solving involving optimization, recursion with memoization, and breaking down complex problems into simpler subproblems, which is common in real-world application development and optimization tasks.

# Example: Fibonacci with DP (common Infosys pattern)
def fib(n, memo={}):
    if n in memo:
        return memo[n]
    if n <= 2:
        return 1
    memo[n] = fib(n-1, memo) + fib(n-2, memo)
    return memo[n]

Which to Prepare for First

Your preparation priority should align with your target role and interview timeline.

Prepare for Meta first if: You are aiming for a software engineering role at a product-based tech company. The rigorous, algorithm-heavy nature of Meta's interview process serves as excellent preparation for most other tech giants. Mastering Meta's large question bank, especially Medium and Hard problems on core data structures, will build a strong foundational skillset that is transferable. The depth required here will make preparing for Infosys's focused set comparatively faster later.

Prepare for Infosys first if: You are specifically targeting IT services, consulting, or application development roles where applied problem-solving and implementation are key. The focused question bank on DP, arrays, and strings allows for efficient, targeted study. This approach is practical if your interview is imminent or if this is your primary career target. However, this preparation may not be sufficient for the depth required at a company like Meta.

In summary, use Meta's vast question bank for deep, comprehensive algorithm training, and Infosys's focused set for efficient, pattern-specific preparation for applied software problems.
