Salesforce vs Yandex: Interview Question Comparison

When preparing for technical interviews at major tech companies, understanding the specific focus areas and difficulty distribution of their coding questions can significantly streamline your study process. Salesforce and Yandex, while both prominent in their respective regions, present distinct interview landscapes. Salesforce, a global CRM leader, has a larger question pool with a greater emphasis on advanced problems. Yandex, Russia's search and tech giant, offers a more moderate set with a stronger focus on foundational and medium-level algorithmic skills. A direct comparison of their question banks reveals clear strategic differences.

Question Volume and Difficulty

The most striking difference is in the total number of questions and their difficulty distribution.

Salesforce maintains a larger repository of 189 questions. The difficulty breakdown is Easy: 27, Medium: 113, Hard: 49. This distribution highlights a significant emphasis on Medium and Hard problems, which together constitute over 85% of their question bank. Preparing for a Salesforce interview means you must be comfortable with complex problem-solving and optimization, as nearly a quarter of their questions are classified as Hard.

Yandex has a smaller set of 134 questions. The breakdown is Easy: 52, Medium: 72, Hard: 10. This profile is markedly different, with a strong skew towards Easy and Medium problems, which make up over 92% of their questions. The presence of Hard problems is minimal. This suggests Yandex interviews may place a higher initial priority on assessing solid foundational knowledge and reliable implementation under typical constraints, rather than on solving the most computationally complex edge cases.

Topic Overlap

Both companies heavily test core data structures and algorithms, but with subtle priority shifts.

The top four topics for both include Array, String, and Hash Table, indicating these are universal essentials. Dynamic Programming (DP) is a top-4 topic for Salesforce but does not appear in Yandex's top four, which instead features Two Pointers. This is a critical distinction.

Salesforce's inclusion of DP as a primary topic aligns with its larger number of Hard questions, as DP problems often involve significant optimization challenges. Yandex's focus on Two Pointers suggests an interview style that frequently tests efficient in-place array/string manipulation and sliding window techniques, which are common in Medium-difficulty problems.

Here is a typical Two Pointers problem you might encounter at Yandex:

def removeDuplicates(nums):
    if not nums:
        return 0
    i = 0
    for j in range(1, len(nums)):
        if nums[j] != nums[i]:
            i += 1
            nums[i] = nums[j]
    return i + 1

In contrast, a Dynamic Programming problem more indicative of Salesforce's style:

def coinChange(coins, amount):
    dp = [float('inf')] * (amount + 1)
    dp[0] = 0
    for coin in coins:
        for x in range(coin, amount + 1):
            dp[x] = min(dp[x], dp[x - coin] + 1)
    return dp[amount] if dp[amount] != float('inf') else -1

Which to Prepare for First

Your preparation priority should be dictated by your target company and current skill level.

If your goal is Yandex, start there. The higher proportion of Easy questions allows you to build confidence with fundamentals. Master the core topics—particularly Arrays, Hash Tables, and Two Pointers—before tackling their Medium problems. You can afford to deprioritize the deepest depths of advanced Dynamic Programming initially.

If your goal is Salesforce, you must prepare for a more demanding interview. Begin by solidifying your understanding of Arrays, Strings, and Hash Tables, but quickly transition to practicing a high volume of Medium problems. Dedicate substantial time to Dynamic Programming, as it is a key differentiator in their question bank. The large number of Hard problems means you should also practice complex problem decomposition and optimization.

For a generalist preparing for both or for the tech interview market broadly, a hybrid approach is effective. Start with the Yandex-focused plan to build a robust foundation across core data structures. This will cover most Easy and many Medium problems common to both companies. Then, layer on the Salesforce-focused depth, specifically drilling into Dynamic Programming patterns and challenging Hard problems to elevate your problem-solving ceiling.
