Accenture vs Cisco: Interview Question Comparison

When preparing for technical interviews at large tech firms, understanding the specific focus areas and question styles of each company can dramatically increase your efficiency. Accenture and Cisco, while both being industry giants, present distinct profiles in their coding interview challenges. A direct comparison of their question banks reveals key differences in volume, difficulty distribution, and core topics, which should inform your preparation strategy.

Question Volume and Difficulty

The most immediate difference is the sheer number of questions. Accenture's catalog is significantly larger, with 144 questions compared to Cisco's 86 questions. This suggests that preparing for Accenture might require a broader sweep of potential problems, while Cisco's more focused list could allow for deeper, more concentrated practice.

The difficulty breakdown further refines this picture:

• Accenture: Easy (65), Medium (68), Hard (11)
• Cisco: Easy (22), Medium (49), Hard (15)

Accenture leans heavily on Easy and Medium questions, with Hard problems making up only about 8% of its total. This indicates a strong emphasis on assessing fundamental problem-solving and clean implementation. Cisco, while having fewer total questions, has a higher proportion of Hard problems (approximately 17%). This points to a greater expectation for candidates to handle complex algorithmic thinking and optimization, even if the core topic list is narrower.

Topic Overlap

Both companies heavily test foundational data structures. Array, String, and Hash Table problems are central to both Accenture and Cisco interviews. Mastering these is non-negotiable for either company.

The key differentiator is in the secondary focus:

• Accenture includes Math as a primary topic. This often involves problems related to number properties, basic arithmetic operations, and mathematical logic.

  # Accenture-style Math example: Count Primes
  def countPrimes(n):
      if n <= 2:
          return 0
      is_prime = [True] * n
      is_prime[0] = is_prime[1] = False
      for i in range(2, int(n ** 0.5) + 1):
          if is_prime[i]:
              for j in range(i*i, n, i):
                  is_prime[j] = False
      return sum(is_prime)
  

• Cisco explicitly highlights Two Pointers as a core topic. This technique is crucial for solving efficient array and string problems, often related to searching, pairing, or in-place manipulation.

  # Cisco-style Two Pointers example: Container With Most Water
  def maxArea(height):
      left, right = 0, len(height) - 1
      max_area = 0
      while left < right:
          width = right - left
          max_area = max(max_area, min(height[left], height[right]) * width)
          if height[left] < height[right]:
              left += 1
          else:
              right -= 1
      return max_area
  

Which to Prepare for First

Start with Cisco. Its focused question set and clear emphasis on Two Pointers provide a sharper, more manageable target. Mastering Arrays, Strings, Hash Tables, and the Two Pointers pattern will build a strong, transferable core. The higher density of Hard problems will also push your algorithmic rigor, which is beneficial for any interview.

Once comfortable with Cisco's core, expand your preparation for Accenture. This involves practicing a larger volume of questions, with particular attention to Math-based problems. The skills honed for Cisco will directly apply to Accenture's foundational topics, and you can then layer on the additional breadth and the specific mathematical reasoning required.
