Interview Date: Not specified
Result: Fail
Difficulty: Average

Interview Process

The interview consisted of two coding rounds.

First Round: File Crawler

  1. Implement an API that takes a file path and returns all files in that path, using a helper function.
  2. Discuss how to scale the first function without coding.
  3. Based on the discussion in the second step, implement an asynchronous job with provided template code.

Second Round: Word Game
The interview involved a word guessing game with two players. One player selects a word, and the other guesses letters. Feedback is provided on whether the guessed letter is a hit (revealed in the word) or a miss (added to a miss array).

  • The interviewer provided an example to ensure understanding.
  • The follow-up was more challenging, as the word chooser could change the word mid-game. The candidate was required to discuss a solution and write pseudocode.

Technical Questions

  1. File System (Asynchronous Programming, API)
  2. Word Guessing Game (String Manipulation, Game, Optimization)

Tips & Insights

  • Be prepared to discuss scalability and optimization strategies during coding interviews.
  • Understanding the problem thoroughly before diving into coding is crucial.
