Yandex vs Expedia: Interview Question Comparison

When preparing for technical interviews at major tech companies, understanding their specific question patterns and focus areas is crucial. Both Yandex, a Russian multinational technology giant, and Expedia Group, a global travel technology company, conduct rigorous coding interviews, but their approaches differ significantly in volume, difficulty, and emphasis. This comparison analyzes their question profiles to help you strategize your preparation.

Question Volume and Difficulty

The most striking difference is the sheer volume of questions associated with each company. Yandex's question bank is notably larger, with 134 questions cataloged, compared to Expedia's 54 questions. This suggests Yandex's interview process is more extensively documented and analyzed by the candidate community, potentially reflecting a longer history of a standardized technical interview loop.

The difficulty distribution also reveals different hiring bars:

• Yandex (E52/M72/H10): The majority of questions are Medium (72), with a substantial number of Easy (52) and a smaller set of Hard (10). This indicates a strong focus on core algorithmic competency, with interviews likely designed to thoroughly assess fundamental problem-solving skills across a moderate difficulty spectrum.
• Expedia (E13/M35/H6): The distribution skews more heavily toward Medium-difficulty questions (35), with fewer Easy (13) and Hard (6) problems. This points to an interview process that aims to evaluate practical, applied coding ability, often skipping the simplest problems to quickly gauge a candidate's proficiency at a consistent, intermediate level.

Topic Overlap

Both companies heavily test foundational computer science concepts, with significant overlap in their top three topics: Array, String, and Hash Table. This is standard for software engineering interviews and should form the bedrock of your preparation for either company.

The key differences lie in their secondary focuses:

• Yandex prominently features Two Pointers as a core topic. This technique is essential for solving optimization problems on sorted arrays or linked lists, such as finding pairs with a target sum or removing duplicates in-place.

  # Two Pointers: Remove Duplicates from Sorted Array
  def removeDuplicates(nums):
      if not nums:
          return 0
      write = 1
      for read in range(1, len(nums)):
          if nums[read] != nums[read-1]:
              nums[write] = nums[read]
              write += 1
      return write
  

- **Expedia** uniquely lists **Greedy Algorithms** as a primary topic. This suggests a focus on problems involving optimal local choices (like interval scheduling or coin change problems), which are common in real-world optimization scenarios relevant to travel and logistics.

Which to Prepare for First

Your preparation priority should be guided by your target company and timeline.

Prepare for Yandex first if: You are interviewing with them, or you want a broad, deep foundation. The larger question bank and emphasis on Two Pointers require dedicated practice. Mastering Yandex's pattern will inherently cover the core (Array, String, Hash Table) needed for Expedia, though you'll need to supplement with Greedy algorithm practice.

Prepare for Expedia first if: It is your primary target, or you have a shorter timeline. The smaller, more focused question set allows for efficient preparation. Solidifying the shared core topics and then drilling Greedy problems is a manageable strategy. However, relying solely on Expedia's scope may leave gaps for the more extensive Yandex interview.

A strategic hybrid approach is to build a foundation using the shared core topics, then branch out based on your target. For most candidates, starting with the high-volume, technique-specific (Two Pointers) profile of Yandex questions will create a stronger overall skill set, making subsequent Expedia-focused Greedy practice more manageable.
