I applied via Campus Placement and was interviewed before Mar 2023. There was 1 interview round.

Round 1 - One-on-one 

(1 Question)

  • Q1. How to calculate optimum Reflux in a distillation column? Would opening a fridge in a room, increase or decrease the temperature of room? Why you want to join us?
  • Ans. 

    To calculate optimum Reflux in a distillation column, one must consider the desired purity of the distillate and the efficiency of the column.

    • Calculate the minimum reflux ratio required for the desired separation using the Fenske equation

    • Consider the efficiency of the column and adjust the reflux ratio accordingly

    • Perform iterative calculations to find the optimum reflux ratio that balances purity and energy consumption

Round 1 - Technical 

(2 Questions)

  • Q1. How is flow affected with change in velocity in a venturimeter.
  • Ans. 

    Velocity change affects flow in a venturimeter.

    • As velocity increases, pressure decreases and vice versa.

    • Flow rate is directly proportional to the square root of pressure difference.

    • Venturimeter is used to measure flow rate in pipes.

    • Flow rate can be calculated using Bernoulli's equation.

  • Answered by AI
  • Q2. Which is better cstr/pfr for zero order reaction.
  • Ans. 

    PFR is better for zero order reaction as it maintains constant concentration throughout the reactor.

    • PFR maintains constant concentration throughout the reactor

    • CSTR may result in concentration gradients

    • PFR is more efficient for zero order reactions

    • CSTR may be more suitable for reactions with changing rate constants
