JPMorgan vs eBay: Interview Question Comparison

When preparing for technical interviews at major companies, understanding their specific focus areas can dramatically improve your efficiency. JPMorgan and eBay, while both requiring strong algorithmic skills, show distinct patterns in their question volume, difficulty distribution, and topical emphasis. A direct comparison reveals how to strategically allocate your study time.

Question Volume and Difficulty

JPMorgan's interview process, with a catalog of approximately 78 questions, presents a broader scope for preparation than eBay's 60. The difficulty breakdown is more telling.

JPMorgan (E25/M45/H8): The distribution is heavily weighted toward medium-difficulty questions (45 out of 78, or ~58%). The high number of easy questions (25) suggests a strong emphasis on assessing fundamental coding fluency and problem-solving clarity, likely in early screening rounds. The relatively small pool of hard questions (8) indicates that while advanced problems may appear, they are not the primary gatekeeper.

eBay (E12/M38/H10): Here, the focus shifts. With only 12 easy questions, the bar for fundamental performance is implicitly higher from the start. The core of the interview is squarely in medium territory (38 questions, ~63%), similar to JPMorgan. However, eBay includes a proportionally larger set of hard questions (10 vs. 8), representing about 17% of its question bank compared to JPMorgan's 10%. This points to a greater likelihood of encountering at least one complex, optimization-heavy problem during the interview loop.

Topic Overlap

Both companies concentrate on a nearly identical set of core data structures and algorithms. The top topics—Array, String, Hash Table, and Sorting—form the essential foundation for both interview experiences.

• Array and String manipulation questions test your ability to handle indices, slicing, and in-place operations.
• Hash Table usage is critical for achieving optimal time complexity via O(1) lookups, frequently applied in problems involving counts, existence checks, or mapping relationships.
• Sorting is both a direct topic (e.g., implement quicksort) and a crucial preprocessing step for more efficient algorithms (e.g., two-pointer techniques on sorted arrays).

The high overlap means that core preparation for one company directly benefits the other. A problem like "Two Sum" is a classic test of hash table application relevant 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 []

Which to Prepare for First

Given the analysis, prioritize preparation for eBay first. This strategy builds a more robust foundation that can then be easily adapted for JPMorgan.

Mastering eBay's question set requires conquering a significant number of medium problems and being prepared to tackle a higher proportion of hard challenges. This level of proficiency will automatically cover the medium-difficulty core that dominates JPMorgan's interview. Once prepared for eBay, transitioning to JPMorgan primarily involves reinforcing fundamentals by practicing a larger set of easy problems to ensure speed and accuracy, while reviewing the slightly smaller set of hard questions.

In essence, preparing for the more demanding difficulty profile (eBay) efficiently elevates your skills to meet the requirements of the broader but slightly less intense profile (JPMorgan). Focus on deep mastery of arrays, strings, hash tables, and sorting, using medium and hard problems as your benchmark for success.
