Initial Phone Screen: (1 HR)

• Conducted with the technical director.
• Covered questions related to previous experience, Clean Code, and SOLID principles.
• Topics included:
  • Polymorphism explanation.
  • Comparison between monolithic and microservices architectures, along with their pros and cons.
  • Task to write code for string reversal.
  • Discussion of various design patterns.
• Personal experience (current job experience, challenges, etc.).

Interview 1: (1 HR)

• Problem: Trapping Rain Water Link
• Allowed to use a personal code editor.
• Required to write code that compiles and includes a few tests.

Interview 2: (1 HR)

• Tasked with creating a linked list data structure from scratch in a personal code editor.
  • Methods included: add, reverse, print.
• Required to write code that compiles and includes a few tests.
• Additionally, tasked with:
  • Using a React sandbox environment.
  • Implementing event binding, like adding text to a list and displaying it on button press.

Interview 3: (1 HR)

• Problem provided:

  // package whatever; // don't place package name! // TASK #1: Implement removeSubStrings // TASK #2: Update to provide more telemetry data // TASK #3: Can I make this multi-threaded, i.e. pass in the same sourceString but with different subStrings // TASK #4: Does TASK #3 provide any real-world benefits?

  def main(str[] args) { str sourceString1 = "JarJarBinksJarJarWiki"; // BinksWiki str sourceString2 = "JarJarBinksJarJar"; // Binks str sourceString3 = "JarJarBinksJarJarWikiJar"; // BinksWikiJar str sourceString4 = "aJarJarBinksJarJarWikiJar"; // aBinksWikiJar

  str subString = "JarJar";
  str finalString = "";
  
  finalString = removeSubStrings(sourceString1, subString);
  System.out.println("sourceString1 finalString: " + finalString + System.lineSeparator());
  
  finalString = removeSubStrings(sourceString2, subString);
  System.out.println("sourceString2 finalString: " + finalString + System.lineSeparator());
  
  finalString = removeSubStrings(sourceString3, subString);
  System.out.println("sourceString3 finalString: " + finalString + System.lineSeparator());
  
  finalString = removeSubStrings(sourceString4, subString);
  System.out.println("sourceString4 finalString: " + finalString + System.lineSeparator());
  

  }

• Completed up to TASK 2 during the interview. However, the interviewer mentioned from the beginning that we would likely only have time for Task 1 and Task 2 at most.

• Implemented in Python in a personal code editor, without the need for compilation or tests. The emphasis was on the problem-solving approach.

Trapping Rain Water Problem as seen on LeetCode.

Create a linked list data structure with functionality such as add, reverse, and print.

TASK #1: Implement removeSubStrings

TASK #2: Update to provide more telemetry data

TASK #3: Can I make this multi-threaded, i.e., pass in the same sourceString but with different subStrings?

TASK #4: Does TASK #3 provide any real-world benefits?

def main(str[] args): str sourceString1 = "JarJarBinksJarJarWiki"; # BinksWiki str sourceString2 = "JarJarBinksJarJar"; # Binks str sourceString3 = "JarJarBinksJarJarWikiJar"; # BinksWikiJar str sourceString4 = "aJarJarBinksJarJarWikiJar"; # aBinksWikiJar

str subString = "JarJar"
str finalString = ""

finalString = removeSubStrings(sourceString1, subString)
System.out.println("sourceString1 finalString: " + finalString + System.lineSeparator())

finalString = removeSubStrings(sourceString2, subString)
System.out.println("sourceString2 finalString: " + finalString + System.lineSeparator())

finalString = removeSubStrings(sourceString3, subString)
System.out.println("sourceString3 finalString: " + finalString + System.lineSeparator())

finalString = removeSubStrings(sourceString4, subString)
System.out.println("sourceString4 finalString: " + finalString + System.lineSeparator())
