Sample Answer for Behavioral Interview Questions - STAR Format

Question: Can you tell me about a time when you had to deal with a difficult supplier or vendor?

Answer (STAR Format):

• Situation: In my previous role as Supply Chain Manager Intern at Connecticut Immigrant & Refugee Coalition, I was responsible for managing inventory and procurement for the organization's retail operation.
• Task: One of our vendors was frequently delivering goods late and with inconsistent quality, which was causing disruptions in our supply chain and leading to unhappy customers.
• Action: I scheduled a meeting with the vendor to discuss these issues and express our concerns. During the meeting, we identified the root cause of the problem, which was ineffective communication and inconsistent specifications. We developed a corrective action plan that included setting clear expectations and timelines, and improving communication channels between the vendor and our organization.
• Result: After implementing these changes, we saw a significant improvement in the vendor's performance. Our inventory was more consistent, and we experienced fewer disruptions in the supply chain. Overall, our customers were much happier with the quality and delivery of goods.

Round 2: Technical Interview Questions - Coding

The technical interview questions are designed to evaluate your coding skills and ability to solve logic-based problems.

1. Given an array of integers, write a function that returns the highest product possible by multiplying three numbers.
2. Write a program to find the nth Fibonacci number using recursion.
3. What is the time complexity of binary search? Explain your answer.
4. Explain the concept of hash tables and provide an example of their use.
5. What is the difference between a stack and a queue? How are they implemented?
6. What is a linked list, and how is it different from an array? Implement a linked list in Python.
7. Explain the difference between a binary search tree and a heap. Write a program to construct either of them.
8. What is the difference between an abstract class and an interface in Java?
9. What is the difference between HashMap and HashSet in Java?
10. What is meant by time and space complexity? Discuss time and space complexity for binary search algorithm.

Sample Answer for Technical Interview Questions - Coding

Question: Given an array of integers, write a function that returns the highest product possible by multiplying three numbers.

Answer:

def highest_product(arr):    if len(arr) < 3:        return None    arr.sort()    return max(arr[0] * arr[1] * arr[-1], arr[-1] * arr[-2] * arr[-3])	

The time and space complexity for the above function is O(n log n) and O(1), respectively.

1. Design a system to manage inventory for an ecommerce store.
2. How would you design a shipping system for an international logistics company?
3. Design a system to manage supply chain operations for a manufacturing company.
4. How would you design a database schema for a hospital management system?
5. Design a system to manage customer complaints for a utility company.
6. How would you design a recommendation system for an ecommerce store?
7. Design a system for monitoring and alerting in a production environment.
8. How would you design a system for tracking and analyzing website traffic?
9. Design a system to manage transportation operations for an airline.
10. How would you design a system for managing and tracking employee performance?
