Interview Process

The interview process consisted of several stages, starting with an initial HR interview followed by two technical interviews focusing on algorithms and system design. I was asked about my previous projects and how I approached problem-solving.

In the first technical interview, I was presented with a problem to implement a simple chat application. I had to demonstrate my thought process in breaking down the problem and the design choices I made. The interviewer seemed pleased with my approach.

The second technical round involved more complex scenarios, including optimizing data transmission and managing user sessions. I also had to present my reasoning behind the solutions I proposed during the discussions. Overall, I felt the interviews were intense but fair, testing both my technical skills and how I communicate my ideas effectively.

Technical Questions

  1. Fibonacci Tree Path Calculation (Tree, DFS)
  2. Tree Distance Sum Problem (Tree, Graph, DFS)

Tips & Insights

Be prepared to explain your thought process clearly and be ready to discuss your previous projects in detail. Communication is key in conveying your ideas effectively during the interview.
