Practice Questions with Detailed Solutions

Section A: Aptitude Questions

Q1. A sum of money doubles itself in 8 years at simple interest. In how many years will it triple itself?

Solution: Let principal = P, Rate = R% For SI: A = P + (P × R × T)/100 At T = 8 years, A = 2P → P = (P × R × 8)/100 → R = 100/8 = 12.5%

For tripling: 3P = P + (P × 12.5 × T)/100 → 2P = (P × 12.5 × T)/100 → T = 200/12.5 = 16 years ✓

Q2. PayPal processes 22 billion transactions per year. If 0.02% of transactions are fraudulent and each fraud costs $45 on average, what is the annual fraud cost?

Solution: Fraudulent transactions = 22,000,000,000 × 0.0002 = 4,400,000 Annual fraud cost = 4,400,000 × $45 = $198,000,000 = $198 million ✓

Q3. A train 250m long passes a pole in 25 seconds. How long will it take to cross a platform 350m long?

Solution: Speed of train = 250/25 = 10 m/s Total distance to cross platform = 250 + 350 = 600m Time = 600/10 = 60 seconds ✓

Q4. In a class of 120 students, 60% are boys. 40% of boys and 50% of girls passed the exam. How many students passed?

Solution: Boys = 120 × 60% = 72; Girls = 48 Boys passed = 72 × 40% = 28.8 ≈ 29 Girls passed = 48 × 50% = 24 Total passed = 29 + 24 = 53 students ✓

Q5. Two pipes A and B can fill a tank in 12 hours and 18 hours respectively. A leak can empty the full tank in 36 hours. If all three are opened simultaneously, how long to fill the tank?

Solution: Rate of A = 1/12, Rate of B = 1/18, Rate of leak = -1/36 Combined rate = 1/12 + 1/18 - 1/36 LCM of 12, 18, 36 = 36 = 3/36 + 2/36 - 1/36 = 4/36 = 1/9 Time = 9 hours ✓

Q6. If the probability that it rains on any given day in Chennai is 0.3, what is the probability that it rains on exactly 2 out of 3 days?

Solution: Using Binomial Distribution: P(X = k) = C(n,k) × p^k × (1-p)^(n-k) n=3, k=2, p=0.3 P(X=2) = C(3,2) × (0.3)² × (0.7)¹ = 3 × 0.09 × 0.7 = 0.189 ✓

Q7. A merchant marks his goods 25% above cost price and gives a 10% discount. What is his profit percentage?

Solution: Let CP = 100 MP = 125 SP = 125 × 90% = 112.5 Profit % = (112.5 - 100)/100 × 100 = 12.5% ✓

Section B: Logical Reasoning

Q8. Five people A, B, C, D, E sit in a row. A is to the right of B. C is to the left of D. E is between A and D. B is second from the left. Who sits in the middle?

Solution: B is 2nd from left → _ B _ _ _ A is to the right of B → A is at position 3, 4, or 5 E is between A and D → E is between them C is to the left of D

Working through: B(2), then try A at 4: _ B _ A _ E between A and D: D at 5, E at position between 4 and 5 → doesn't work Try: B(2), A(3), E(4), D(5), C(1) C < D ✓, E between A(3) and D(5) ✓, A right of B ✓ Middle position (3rd) = A ✓

Q9. Find the next number in the series: 2, 6, 12, 20, 30, 42, ?

Solution: Differences: 4, 6, 8, 10, 12, 14 The differences increase by 2 each time. Next difference = 14, so next number = 42 + 14 = 56 ✓ Pattern: n(n+1) → 1×2, 2×3, 3×4, 4×5, 5×6, 6×7, 7×8 = 56 ✓

Section C: Coding Questions

Q10. Find the longest substring without repeating characters.

def lengthOfLongestSubstring(s: str) -> int:
    char_index = {}
    max_len = 0
    left = 0
    
    for right in range(len(s)):
        if s[right] in char_index and char_index[s[right]] >= left:
            left = char_index[s[right]] + 1
        char_index[s[right]] = right
        max_len = max(max_len, right - left + 1)
    
    return max_len

# Example: "abcabcbb" → 3 ("abc")
# Time: O(n), Space: O(min(m,n)) where m = charset size

Explanation: Sliding window approach. Maintain a window [left, right]. When a duplicate is found, move left past the previous occurrence. Track max window size throughout.

Q11. Given a list of transactions (positive = credit, negative = debit), find the maximum subarray sum (Kadane's Algorithm applied to PayPal-style financial data).

def maxSubarraySum(transactions: list) -> int:
    max_sum = transactions[0]
    current_sum = transactions[0]
    
    for i in range(1, len(transactions)):
        current_sum = max(transactions[i], current_sum + transactions[i])
        max_sum = max(max_sum, current_sum)
    
    return max_sum

# Example: [-2, 1, -3, 4, -1, 2, 1, -5, 4]
# Output: 6 (subarray [4,-1,2,1])
# Time: O(n), Space: O(1)

Q12. Implement a LRU Cache, a common PayPal interview problem for caching payment sessions.

from collections import OrderedDict

class LRUCache:
    def __init__(self, capacity: int):
        self.cache = OrderedDict()
        self.capacity = capacity
    
    def get(self, key: int) -> int:
        if key not in self.cache:
            return -1
        self.cache.move_to_end(key)
        return self.cache[key]
    
    def put(self, key: int, value: int) -> None:
        if key in self.cache:
            self.cache.move_to_end(key)
        self.cache[key] = value
        if len(self.cache) > self.capacity:
            self.cache.popitem(last=False)

# Time: O(1) for both get and put
# Space: O(capacity)

Q13. Check if a given string is a valid balanced parentheses expression (used in expression parsing for payment rule engines).

def isValid(s: str) -> bool:
    stack = []
    mapping = {')': '(', '}': '{', ']': '['}
    
    for char in s:
        if char in mapping:
            top = stack.pop() if stack else '#'
            if mapping[char] != top:
                return False
        else:
            stack.append(char)
    
    return not stack

# Examples:
# "()" → True
# "()[]{}" → True  
# "(]" → False
# Time: O(n), Space: O(n)

Q14. Binary Search on a rotated sorted array, find if a target value exists.

def search(nums: list, target: int) -> int:
    left, right = 0, len(nums) - 1
    
    while left <= right:
        mid = (left + right) // 2
        if nums[mid] == target:
            return mid
        
        # Left half is sorted
        if nums[left] <= nums[mid]:
            if nums[left] <= target < nums[mid]:
                right = mid - 1
            else:
                left = mid + 1
        else:  # Right half is sorted
            if nums[mid] < target <= nums[right]:
                left = mid + 1
            else:
                right = mid - 1
    
    return -1

# Time: O(log n), Space: O(1)

Q15. Detect a cycle in a linked list (Floyd's Tortoise and Hare algorithm).

class ListNode:
    def __init__(self, val=0, next=None):
        self.val = val
        self.next = next

def hasCycle(head: ListNode) -> bool:
    slow = head
    fast = head
    
    while fast and fast.next:
        slow = slow.next
        fast = fast.next.next
        if slow == fast:
            return True
    
    return False

# Time: O(n), Space: O(1)
# Used in PayPal's transaction graph processing to detect circular dependencies

HR Interview Questions & Sample Answers

HR Q1: Why do you want to work at PayPal?

Sample Answer: "PayPal is at the intersection of finance and technology, which is exactly where I want to build my career. What excites me most is the scale, building systems that handle billions of transactions and protect hundreds of millions of users requires engineering excellence at every level. I also admire PayPal's mission of democratizing financial services, especially in emerging markets like India. The work being done at the Chennai and Bangalore centers on fraud detection using ML and real-time payments aligns perfectly with my interests in distributed systems and data engineering."

HR Q2: Describe a challenging project and how you overcame obstacles.

Sample Answer: "During my final year project, I built a peer-to-peer payment simulation system. Midway through, I discovered our transaction consistency model had a race condition under concurrent loads. I had to redesign the locking mechanism under time pressure. I researched optimistic locking vs. pessimistic locking, consulted my professor, and implemented a version-based optimistic locking system. This not only fixed the bug but also improved throughput by 40%. The experience taught me to test early with concurrent scenarios and to stay calm under pressure."

HR Q3: Where do you see yourself in 5 years?

Sample Answer: "In five years, I see myself as a senior engineer at PayPal who has shipped at least 2–3 major product features end-to-end. I want to develop deep expertise in distributed payment systems and potentially take on a technical lead role. I'm also passionate about mentoring, I'd love to guide new graduates joining the team, just as I hope to be guided by experienced engineers here. Long-term, I want to contribute to PayPal's growth in the APAC region, possibly in an architecture or product strategy capacity."

HR Q4: How do you handle disagreements with teammates?

Sample Answer: "I believe healthy disagreement drives better outcomes. When I disagree, I first make sure I fully understand the other person's perspective by asking clarifying questions. Then I present my view with data and reasoning, not emotion. If we're still at an impasse, I suggest we prototype or test both approaches and let results decide. In one instance during a hackathon, my teammate and I disagreed on database choice. We built a small benchmark, and the data clearly showed one option was faster. We went with that, and both of us felt good about the process."

HR Q5: What is your greatest weakness?

Sample Answer: "I sometimes over-engineer solutions, I get excited about elegant, scalable designs even when a simpler solution would do. I've been actively working on this by applying the YAGNI principle (You Aren't Gonna Need It) and time-boxing my design phases. In my last project, I consciously shipped a simpler version first, gathered user feedback, and then refactored. It was a valuable exercise in pragmatism over perfectionism, and the end product was better for it."
