Accenture vs Expedia: Interview Question Comparison

When preparing for technical interviews, understanding company-specific patterns is crucial for efficient study. Accenture and Expedia, while both assessing core software engineering skills, present distinct profiles in question volume, difficulty distribution, and topical focus. This comparison breaks down their technical interview landscapes to help you prioritize your preparation.

Question Volume and Difficulty

The data reveals a significant difference in the breadth of documented questions.

Accenture maintains a much larger public question bank with 144 questions. Its difficulty distribution is heavily weighted towards easier and medium problems: 65 Easy (45%), 68 Medium (47%), and only 11 Hard (8%). This suggests Accenture's technical screening often focuses on assessing solid fundamentals and reliable problem-solving on common patterns, rather than on highly complex, niche algorithms. The high volume indicates a wide variety of potential questions, making pattern recognition across their problem set a key strategy.

Expedia has a more curated set of 54 questions. The difficulty spread is 13 Easy (24%), 35 Medium (65%), and 6 Hard (11%). Notably, the proportion of Medium questions is substantially higher than Accenture's. This points to an interview process that, while involving fewer total problem types, expects candidates to comfortably handle moderate complexity. The lower total count may mean questions are reused more frequently or that the interview loop is more focused on a deeper evaluation of a smaller set of concepts.

# Example of a common "Medium" array problem (Two Sum II - Input Array Is Sorted)
def two_sum(numbers, target):
    left, right = 0, len(numbers) - 1
    while left < right:
        current_sum = numbers[left] + numbers[right]
        if current_sum == target:
            return [left + 1, right + 1]
        elif current_sum < target:
            left += 1
        else:
            right -= 1
    return []

# This pattern is highly relevant for both companies.

Topic Overlap

Both companies emphasize the foundational pillars of technical interviews: Array, String, and Hash Table problems. This strong overlap means mastering these topics provides high-value preparation for either company.

• Array/String/Hash Table: Expect problems involving traversal, two-pointers, sliding windows, and mapping. These form the core of most assessments.
• Math (Accenture): Accenture's specific inclusion of Math suggests a higher likelihood of numerical problems, digit manipulation, or basic arithmetic logic.
• Greedy (Expedia): Expedia's unique call-out of Greedy algorithms indicates you should be prepared to recognize problems where a locally optimal choice leads to a global solution, such as in interval scheduling or coin change (canonical) problems.

# Example highlighting Hash Table (common) and Greedy (Expedia-specific) logic
def partition_labels(s):
    last_occurrence = {char: i for i, char in enumerate(s)}  # Hash Table
    result = []
    start = end = 0
    for i, char in enumerate(s):
        end = max(end, last_occurrence[char])  # Greedy: extend partition as far as needed
        if i == end:
            result.append(end - start + 1)
            start = i + 1
    return result

Which to Prepare for First

Start with Accenture. Its vast question bank dominated by Easy and Medium problems on the most common topics (Array, String, Hash Table) provides an ideal training ground. Solving a broad set of these problems will cement the fundamental patterns and build your coding speed and confidence. This foundation is directly transferable and completely relevant for Expedia.

Once comfortable with Accenture's pattern, pivot to Expedia preparation. Focus on deepening your understanding of Medium-difficulty problems and specifically practice Greedy algorithms. The smaller question set allows for more targeted, repeated practice. Since you've already built core skills, you can concentrate on the increased complexity and Expedia's specific emphasis.

In short: use Accenture's breadth to build your core competency, then use Expedia's focused, medium-heavy set to sharpen and specialize your skills.
