Interview Preparation Tips

Interview preparation tips for other job seekers - There are 3 rounds, 2 technical and 1 HR.
In my case Two technical interviews were smooth. The panel got impressed and they even sent connection requests in LinkedIn. They were happy. And, informed me about final round.

The strange part is the HR never called me. And, after couple of days I dropped a mail but no response. It was quite unprofessional.

(1 Question)

  • Q1. How Decision tree works
  • Ans. 

    Decision tree is a predictive modeling tool that uses a tree-like graph of decisions and their possible consequences.

    • Decision tree splits data into subsets based on the value of a certain attribute

    • It recursively divides data into smaller subsets until a stopping criterion is met

    • Each internal node represents a decision based on an attribute, and each leaf node represents the outcome

Round 2 - Technical 

(1 Question)

  • Q1. How pressure varies wrt temperature
  • Ans. 

    Pressure generally increases with temperature due to the kinetic energy of gas molecules.

    • Pressure is directly proportional to temperature in a closed system (Boyle's Law).

    • As temperature increases, gas molecules move faster and collide with the container walls more frequently, increasing pressure.

    • For example, a balloon inflated indoors may burst when taken outside on a hot day due to increased pressure from higher tempe
