Adobe vs Salesforce: Interview Question Comparison
Compare coding interview questions at Adobe and Salesforce — difficulty levels, topic focus, and preparation strategy.
When preparing for technical interviews at major tech companies, understanding the specific patterns and problem types they favor can significantly streamline your study process. Adobe and Salesforce both ask algorithmic questions that test fundamental data structure and algorithm knowledge, but their question distributions and focus areas differ in meaningful ways. This comparison breaks down their question volume, difficulty distribution, and core topics to help you prioritize your preparation.
Question Volume and Difficulty
Adobe's question pool is slightly larger, with 227 total questions compared to Salesforce's 189. However, the difficulty distribution reveals a more significant strategic difference.
Adobe's breakdown (Easy: 68, Medium: 129, Hard: 30) shows a strong emphasis on Medium-difficulty problems. Nearly 57% of their questions fall into this category, indicating that interviewers are keenly interested in a candidate's ability to handle nuanced problems that require combining multiple concepts or optimizing beyond a brute-force solution. The relatively lower proportion of Hard questions (13%) suggests that while advanced problems are in the mix, the core of the interview is built on solid, intermediate problem-solving.
Salesforce's distribution (Easy: 27, Medium: 113, Hard: 49) tells a different story. While Medium problems are also the majority (60%), Salesforce has a notably higher proportion of Hard questions—about 26% of its total pool. This indicates that interviews at Salesforce are more likely to push into complex algorithmic territory, testing deeper optimization, advanced dynamic programming, or intricate graph manipulations. The lower number of Easy questions suggests they expect candidates to arrive with strong fundamentals already in place.
Topic Overlap
Both companies heavily test core computer science fundamentals. Array, String, and Hash Table problems are prevalent at both, forming the backbone of their interviews. These topics are essential for questions involving data manipulation, searching, and frequency counting.
A key differentiator is the fourth most frequent topic for each:
- Adobe favors Two Pointers. This technique is often used for problems involving sorted arrays, palindromes, or sliding windows (a variant of two pointers). Expect problems where you need to find pairs, remove duplicates in-place, or compare strings/arrays from both ends.
- Salesforce emphasizes Dynamic Programming (DP). This points to a focus on optimization problems, recursive thinking with memoization, and breaking down complex problems into overlapping subproblems. Questions may involve classic DP patterns like knapsack, longest common subsequence, or unique paths.
Here is a simple example illustrating the difference in approach for a pair-sum problem:
# Adobe-style: Two Pointers (assumes sorted input)
def two_sum_two_pointers(nums, target):
left, right = 0, len(nums) - 1
while left < right:
current_sum = nums[left] + nums[right]
if current_sum == target:
return [left, right]
elif current_sum < target:
left += 1
else:
right -= 1
return []
# Salesforce-style: Could involve DP for a variant (e.g., count of ways)
def count_ways_dp(nums, target):
# DP array where dp[i] represents ways to achieve sum i
dp = [0] * (target + 1)
dp[0] = 1
for num in nums:
for i in range(target, num - 1, -1):
dp[i] += dp[i - num]
return dp[target]
Which to Prepare for First
Start with the common foundation. Mastering Arrays, Strings, Hash Tables, and core sorting/searching algorithms will benefit you for both companies. Practice a wide range of Medium-difficulty problems, as they dominate both question pools.
If your target is Adobe, prioritize fluency with the Two Pointers technique and its related patterns like sliding window. Ensure you can cleanly implement these solutions on sorted and unsorted data.
If your target is Salesforce, you must dedicate significant time to Dynamic Programming. Move beyond simple Fibonacci memorization to tackle classic medium-hard DP problems. Understanding state definition, transition, and space optimization is crucial given their higher frequency of Hard questions.
A practical strategy is to build your core skills first, then deep-dive into the differentiating topic (Two Pointers or DP) based on your interview schedule. Since both companies test Medium problems most, a candidate well-prepared for one will have a strong base for the other, needing primarily a topic-specific tune-up.
