PhonePe vs Expedia: Interview Question Comparison

Preparing for technical interviews requires understanding a company's specific focus areas. PhonePe and Expedia, while both tech-driven, have distinct engineering challenges reflected in their interview question patterns. PhonePe's data shows 102 total questions (36 Easy, 63 Medium, 36 Hard), indicating a rigorous, high-volume process. Expedia's set is smaller at 54 questions (13 Easy, 35 Medium, 6 Hard), suggesting a more moderate but still challenging interview loop. This comparison analyzes their question volume, difficulty distribution, and core topics to help you strategize your preparation.

Question Volume and Difficulty

PhonePe's interview process is quantitatively demanding. With 102 cataloged questions, candidates face a broader pool of potential problems. The difficulty distribution (E3/M63/H36) reveals a heavy emphasis on Medium and Hard problems—nearly 97% of their questions fall into these categories. This signals that PhonePe prioritizes complex problem-solving and algorithmic depth, expecting candidates to handle non-trivial challenges consistently.

Expedia's question bank is roughly half the size at 54 problems. Its distribution (E13/M35/H6) is more balanced, with a strong majority (65%) being Medium difficulty. The relatively low number of Hard questions (just 6, or 11%) suggests Expedia's interviews, while still technically rigorous, may place greater weight on foundational competency and practical implementation over extreme algorithmic optimization. The volume indicates a more focused, predictable question scope.

Topic Overlap

Both companies emphasize core computer science fundamentals, but with different secondary priorities.

Shared Core Topics: Array, Hash Table. These are universal building blocks for data manipulation and lookup efficiency, essential for any software engineering role.

PhonePe's Distinct Focus: Dynamic Programming and Sorting appear as major topics. DP questions often relate to optimization problems in financial transactions or resource allocation, while advanced sorting aligns with data processing pipelines. The high volume of Hard questions frequently involves these complex patterns.

Expedia's Distinct Focus: String and Greedy algorithms are prominent. String manipulation is critical for processing travel itineraries, user inputs, and data parsing. Greedy algorithms often apply to optimization problems like scheduling, routing, or cost minimization—common in travel logistics.

Here is a typical problem illustrating a core topic for each:

# PhonePe-style: DP (Medium/Hard)
# Problem: Count ways to make a payment using coin denominations
def count_ways(coins, amount):
    dp = [0] * (amount + 1)
    dp[0] = 1
    for coin in coins:
        for i in range(coin, amount + 1):
            dp[i] += dp[i - coin]
    return dp[amount]

Which to Prepare for First

Prepare for PhonePe first if you are aiming for roles at both companies. Its broader question bank and higher concentration of Hard problems, especially in Dynamic Programming, will force you to build deeper algorithmic mastery. Succeeding in PhonePe-level preparation naturally covers the Medium-difficulty core of Expedia's interview. Mastering PhonePe's patterns—like complex DP states and efficient sorting—ensures you are over-prepared for Expedia's technical screen.

If you are interviewing only at Expedia, you can focus more narrowly. Prioritize Array, String, and Hash Table problems at the Medium level, with selective practice on Greedy algorithms. Ensure you are proficient in string manipulation, hash map utilization for lookups, and common array traversal patterns. Since Hard problems are less frequent, allocate most of your time to perfecting Medium-difficulty solutions with clean, bug-free code.

Regardless of your target, always practice communicating your thought process clearly. PhonePe's harder problems demand explaining complex optimizations, while Expedia's focus on practical topics requires connecting your solution to real-world scenarios like data processing or scheduling.
