Duration: 60 minutes
Total Questions: 60

Round: Technical Interview
Experience: The questions were basic, some where well known like reversing a link list using recursion, designing of car parking lot using concept of oops, find tree height/diameter, etc.
Tips: 1. They ask you to write complete code on paper. This sometimes turn out to be a challenging task when you don't have compiler to correct you on basic things. Practice writing codes on paper.
2. They surely ask questions on oops, like polymorphism, inheritance, etc. besides their definition, also practice writing sudo codes to explain them

Round: HR Interview
Experience: Mainly i was asked questions on my internship experience and POR's.
Tips: They will try to grill you on some questions like 'Why we should hire you?', have a clear reason in your mind. Your other answers should not contradict with your reasons

General Tips: I don't know about other colleges but HP recruits small number of students from my university. Coding questions were average level and can easily be tackled. Many students were rejected after HR interview so don't take it lightly. They do grill you in a very good style if they are in doubt about your selection

  • Q1. What is sub cooling in air conditioning?
  • Ans. 

    Sub cooling in air conditioning is the process of cooling the refrigerant below its saturation temperature to improve system efficiency.

    • Sub cooling increases the efficiency of the air conditioning system by ensuring the refrigerant is in a liquid state before entering the expansion valve.

    • It helps in preventing flash evaporation of the refrigerant, which can lead to inefficiencies in the system.

    • Sub cooling is typically ...

    • The higher the ISEER rating, the more energy efficient the air conditioner is.

    • ISEER rating helps consumers compare the energy efficiency of...

  • Q5. Explain 1 ton cooling concept
  • Ans. 

    1 ton cooling concept refers to the amount of heat required to melt one ton of ice in a 24-hour period.

    • 1 ton of cooling is equal to 12,000 BTUs per hour

    • It is commonly used in the HVAC industry to measure the cooling capacity of air conditioning systems

    • For example, a 2-ton air conditioner can remove 24,000 BTUs of heat per hour

  • Answered by AI
  • Q6. Relation between current, voltage and power
  • Ans. 

    The relationship between current, voltage, and power is described by Ohm's Law, which states that current is directly proportional to voltage and inversely proportional to resistance.

    • Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.

    • Power (P) is calculated using the formula P = V * I, where P is power, V is voltage, and I is current.

    • In a circuit with a constant resistance, an increa...

  • Q7. Conversion from BTU to watts and vice versa
  • Ans. 

    1 BTU is approximately equal to 0.29307107 watts. To convert BTU to watts, multiply by 0.29307107. To convert watts to BTU, divide by 0.29307107.

    • 1 BTU = 0.29307107 watts

    • To convert BTU to watts, multiply by 0.29307107

    • To convert watts to BTU, divide by 0.29307107
