Interview Process

The interview process consisted of four rounds, but initially, only the first half was scheduled, which included one coding interview and one system design interview. Each round began with 10-15 minutes of behavioral questions, followed by 20-25 minutes of technical questions, and concluded with 5-10 minutes for the candidate to ask questions. The time was quite tight.

Technical Questions

  1. Coding Question: Design and implement a Phone Directory with the following requirements:

    • Functionality:
      • assign(number): Marks the specified number as assigned. If the number has not been assigned yet, it successfully assigns it.
      • get(): Returns an unassigned phone number and marks it as assigned.
    • Constraints:
      • All operations must be performed in memory.
      • External databases are not allowed.
  2. System Design Question: Design a Store Inventory System suitable for e-commerce scenarios. This system essentially supports inventory management and querying for medium to large e-commerce platforms.

Tips & Insights

During the behavioral question segment, candidates should be prepared to discuss conflict resolution, technical challenges faced, improvements made to technology or processes, and how they achieved their goals. Examples should be provided for each question, and candidates should expect follow-up questions based on their responses. The interviewers expressed positive feedback during the interview, indicating a hopeful outcome. However, after the interview, the HR informed the candidate that they were moving forward with other candidates who were a closer fit for their needs.
