Infosys vs Wix: Interview Question Comparison

When preparing for technical interviews, understanding the company's specific focus areas is crucial for efficient study. Infosys and Wix represent two distinct ends of the interview spectrum: a global IT services giant and a focused product-based company. Their publicly available question profiles reveal significant differences in volume, difficulty, and core topics, which directly shape how you should prepare.

Question Volume and Difficulty

The most immediate difference is scale. Infosys's list of 158 questions is nearly three times the size of Wix's 56 questions. This volume suggests Infosys has a broader, more standardized hiring process, potentially drawing from a large, common question bank used across many roles and experience levels.

The difficulty distribution further highlights their different approaches:

• Infosys (E42/M82/H34): The majority of questions are Medium difficulty (82), with a substantial number of Hard (34) and Easy (42) problems. This wide spread indicates their process is designed to assess a range of foundational to advanced problem-solving skills, possibly filtering candidates through progressively challenging rounds.
• Wix (E16/M31/H9): The focus is overwhelmingly on Medium difficulty (31 out of 56). The low number of Hard questions (9) suggests their interview loop prioritizes strong, reliable implementation of common patterns over solving esoteric, complex algorithms. The process is more targeted toward practical coding ability for product development.

Topic Overlap

Both companies emphasize Array and String manipulation, which are foundational to almost all coding interviews. Mastering operations like two-pointer techniques, sliding window, and string parsing is essential for both.

The divergence in secondary topics reveals their engineering priorities:

• Infosys heavily tests Dynamic Programming and Math. DP questions assess advanced problem decomposition and optimization, while Math problems test logical reasoning and edge-case handling. This aligns with a services company that may work on diverse, algorithmically complex backend systems.
• Wix frequently tests Hash Table and Depth-First Search. Hash tables are the cornerstone of efficient data lookup, critical for web application performance. DFS, often used in tree and graph traversal, points to Wix's focus on UI frameworks, DOM manipulation, and nested component structures—core concerns for a website builder platform.

Here is a typical question that might appear at both companies, solved using a hash table:

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 []

# Example: two_sum([2, 7, 11, 15], 9) -> [0, 1]

Which to Prepare for First

Your preparation order should be guided by your goals and the nature of the interviews.

Prepare for Wix first if you are targeting product-based roles or have an interview soon. The smaller, more focused question set on core data structures (Arrays, Strings, Hash Tables) and fundamental algorithms (DFS) allows for a deep, confident mastery. You can efficiently cover the high-probability topics. Solid performance on Medium-difficulty problems is key.

Prepare for Infosys first if you are building a broad foundation for the IT services industry or have more time. The vast question bank requires a wider study plan. You must build competency across more areas, especially Dynamic Programming and Math. Tackling this broader curriculum first will inherently cover the foundational topics needed for Wix, making a subsequent switch easier. Be prepared for a wider difficulty range.

In short, use Wix's profile for a targeted, efficient study sprint. Use Infosys's profile for a comprehensive, foundational knowledge grind.
