Adobe vs Expedia: Interview Question Comparison

When preparing for technical interviews, understanding company-specific patterns is crucial for efficient study. Adobe and Expedia represent two distinct points on the tech interview spectrum: one is a large product-focused software giant with a deep question bank, and the other is a major online travel company with a more concentrated set of problems. A direct comparison of their reported question profiles reveals clear strategic differences in preparation.

Question Volume and Difficulty

The most striking difference is the sheer volume of questions. Adobe's list of 227 questions is over four times larger than Expedia's 54. This suggests Adobe's interview process may pull from a broader, more established problem set, potentially encountered across different teams or over a longer period of time.

The difficulty distribution also differs. Using the common Easy (E), Medium (M), Hard (H) classification:

• Adobe (E68/M129/H30): The focus is squarely on Medium-difficulty problems, which make up about 57% of the list. The presence of 30 Hard problems indicates that candidates should be prepared for complex algorithmic challenges, especially for more senior roles.
• Expedia (E13/M35/H6): The emphasis is also on Medium problems (roughly 65% of the list), but the overall count is much lower. Notably, Hard problems are relatively scarce. This could point to an interview process that prioritizes foundational problem-solving and clean code over highly optimized solutions for obscure edge cases.

This disparity means preparing for Adobe requires grinding a larger number of problems, with significant time dedicated to mastering Medium and Hard questions. Expedia preparation can be more focused on core patterns with a strong emphasis on Medium-level mastery.

Topic Overlap

Both companies heavily test fundamental data structures. Array, String, and Hash Table problems are central to both. This is excellent news for candidates, as mastering these topics provides a strong foundation for either interview.

The key differentiators are the secondary focuses:

• Adobe prominently features Two Pointers. This technique is essential for solving a wide range of problems involving sorted arrays, palindromes, or searching for pairs.

# Two Pointers: Pair with Target Sum
def pair_with_target_sum(arr, target):
    left, right = 0, len(arr) - 1
    while left < right:
        current_sum = arr[left] + arr[right]
        if current_sum == target:
            return [left, right]
        if current_sum < target:
            left += 1
        else:
            right -= 1
    return [-1, -1]

• Expedia lists Greedy as a key topic. Greedy algorithms are used for optimization problems (like interval scheduling or minimum cost) where a locally optimal choice leads to a global solution.

# Greedy: Minimum Number of Coins
def min_coins(coins, amount):
    coins.sort(reverse=True)
    count = 0
    for coin in coins:
        if amount >= coin:
            count += amount // coin
            amount %= coin
    return count if amount == 0 else -1

Which to Prepare for First

Your preparation priority should be dictated by your interview timeline and the role's seniority.

Prepare for Adobe first if: You are interviewing for a mid-to-senior level software engineering role, have more time to prepare, or want to tackle a broader set of challenging problems. Mastering Adobe's list will inherently cover almost all of Expedia's core topics (Array, String, Hash Table) while adding deep practice in Two Pointers. The Hard problems will push your algorithmic limits.

Prepare for Expedia first if: You are on a tighter schedule, are newer to technical interviews, or are applying for a role where system design or behavioral fit might be weighted more heavily. A solid grasp of core data structures and Medium-difficulty problems, with specific attention to Greedy patterns, will cover the majority of their question profile efficiently.

In practice, a strong candidate should be comfortable with all the overlapping topics. Starting with Expedia's focused list can build confidence and core competency, which can then be expanded upon with Adobe's larger and more difficult problem set for comprehensive preparation.
