Google vs Wix: Interview Question Comparison

When preparing for technical interviews, the company you're targeting dramatically changes your preparation strategy. Google and Wix represent two distinct ends of the spectrum in software engineering interviews: one is a massive, established tech giant with a deeply standardized process, and the other is a product-focused scale-up with a more concentrated interview scope. Understanding their differences in question volume, difficulty distribution, and core topics is essential for efficient study.

Question Volume and Difficulty

The sheer scale of available practice material highlights a fundamental difference in their interview footprints.

Google has a vast, well-documented history of interview questions, with 2217 cataloged problems. The difficulty distribution (588 Easy, 1153 Medium, 476 Hard) reveals a strong emphasis on Medium-difficulty problems, which form the backbone of their typical onsite rounds. The high volume indicates that while patterns repeat, you must be prepared for a wide variety of problem formulations and twists on core concepts. You cannot "game" the system by studying a small set; depth and breadth are required.

Wix, by contrast, has a much more focused question bank of 56 problems. The distribution (16 Easy, 31 Medium, 9 Hard) shows a similar skew toward Medium problems, but the total count is orders of magnitude smaller. This suggests their interview process is more contained, potentially revolving around a more consistent set of problem types or domains relevant to their product work (e.g., web application logic, DOM tree manipulation). Preparation can be more targeted.

Topic Overlap

Both companies heavily test foundational data structures, but their specialization diverges.

Shared Core (Array, String, Hash Table): Both lists prioritize these fundamental topics. For any software engineering role, mastery here is non-negotiable. You must be fluent in two-pointer techniques, sliding window, string manipulation, and hash map-based lookups and caching.

# Example: Two-pointer for a sorted array (common to both)
def two_sum_sorted(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 []

Diverging Specialties:

• Google's Dynamic Programming (DP): The prominence of DP aligns with Google's focus on algorithmic optimization and solving complex, scalable problems. Expect questions on classic DP patterns (knapsack, longest common subsequence, state machines) and more novel applications.
• Wix's Depth-First Search (DFS): The inclusion of DFS as a top topic likely reflects the importance of tree and graph traversal in web development—manipulating the DOM tree, processing nested UI components, or handling state in complex applications. This is a practical, domain-relevant skill for a company building website tools.

Which to Prepare for First

Your priority depends on your goals and timeline.

If you are preparing specifically for Wix, start there. The smaller, more focused question set allows you to achieve coverage and confidence more quickly. Master the shared core (Array, String, Hash Table) and then dive deeply into tree/graph problems using DFS and related algorithms (BFS, recursion). This targeted approach is efficient.

If your goal is Google, or FAANG-level companies in general, you must begin with Google's core topics. The required breadth means you need a longer runway. Start with the foundational trio, then move systematically into Dynamic Programming, as it is a major differentiator and a high-weight topic in their interviews. Preparing for Google's rigor will inherently cover the technical depth needed for Wix, but not necessarily the specific domain context (like DFS for UI trees).

In short: Prepare for the hardest, broadest interview first. If Google is on your roadmap, that preparation becomes your foundation. If you are only targeting product companies like Wix, you can optimize your study for their specific technical profile.
