Interview Process

The interview consisted of a one-way video format with four questions designed to assess both technical knowledge and communication skills.

Technical Questions

  1. Describe a project you have worked on to a non-technical person. (Communication, Project Management)
  2. Describe the worst-case time complexity for the following scenarios:
    • Removing an element from a sorted array
    • Checking if a key is in a hash table
    • Removing the minimum element from a min-heap
    • Finding the i-th element in a sorted array (Algorithm Complexity, Data Structures)
  3. Explain if multithreading is always faster than single threading, with examples. (Multithreading, Performance Optimization)
  4. Design a hotel booking system without using a database, only using in-memory data structures. (System Design, Data Structures)

Tips & Insights

  • Focus on clear communication, especially when explaining technical concepts to non-technical individuals.
  • Be prepared to discuss time complexities in detail, as well as practical examples of algorithm performance.
  • Understand the nuances of multithreading versus single threading, and be ready to provide real-world scenarios to support your explanation.
  • When designing systems, think critically about the requirements and constraints, especially when limited to in-memory solutions.
