Meta vs Airbnb: Interview Question Comparison

When preparing for technical interviews at top tech companies, understanding the specific focus and expectations of each can dramatically improve your efficiency. Meta and Airbnb, while both demanding strong algorithmic skills, present distinct landscapes in terms of question volume, difficulty distribution, and topic emphasis. This comparison breaks down their key differences to help you tailor your preparation strategy.

Question Volume and Difficulty

The most striking difference is the sheer scale of their question pools. Meta's list is vast, with 1387 questions categorized by difficulty: 414 Easy, 762 Medium, and 211 Hard. This immense volume reflects Meta's broad hiring needs and the likelihood you'll encounter a problem you haven't seen before. Preparation must focus on mastering patterns and fundamentals, not memorization.

In contrast, Airbnb's list is significantly more focused, with only 64 questions total: 11 Easy, 34 Medium, and 19 Hard. The smaller pool suggests a higher probability of encountering a known problem or a close variant. However, this does not mean preparation is easier; it means depth of understanding on these specific problems is critical. The high proportion of Medium and Hard questions (over 80%) indicates a strong emphasis on complex problem-solving.

Topic Overlap

Both companies prioritize core data structures. Array, String, and Hash Table appear in the top four topics for both, making these absolute fundamentals.

Meta's top topics are Array, String, Hash Table, and Math. The inclusion of Math highlights a need for comfort with numerical algorithms, bit manipulation, and probability. You can expect problems that combine these core structures with logical twists.

Airbnb's top topics are Array, Hash Table, String, and Dynamic Programming. The prominence of Dynamic Programming is a key differentiator. Airbnb's list often includes complex DP problems involving string matching, partitioning, or optimization, requiring strong skills in state definition and memoization.

Here is a simple example of a Hash Table problem common to both:

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 []

And an example of a Dynamic Programming problem more emphasized at Airbnb:

def coin_change(coins, amount):
    dp = [float('inf')] * (amount + 1)
    dp[0] = 0
    for i in range(1, amount + 1):
        for coin in coins:
            if i - coin >= 0:
                dp[i] = min(dp[i], dp[i - coin] + 1)
    return dp[amount] if dp[amount] != float('inf') else -1

Which to Prepare for First

Start with Meta's fundamentals. Its massive question list forces a broad and deep understanding of core algorithms and data structures. Mastering Array, String, Hash Table, and recursion/backtracking (implied by its common topics) builds a versatile foundation applicable anywhere. If you prepare for Meta, you will cover most of the base knowledge needed for Airbnb.

Then, pivot to Airbnb's focused list. Use it for targeted, deep practice. Specifically, grind their Dynamic Programming and graph problems, as these are highlighted. The smaller pool allows for thorough analysis of each problem's nuances, edge cases, and potential follow-ups, which is crucial given the high difficulty weight.

In summary, use Meta's breadth to build your general algorithmic muscle, then apply that strength to master the depth and specific patterns in Airbnb's list.
