Interview Questionnaire
2 Questions
- Q1. Coding questions on data structures and oops
- Q2. Various questions on cv, projects, por's, etc
Interview Preparation Tips
Experience: Questions were normal like any other aptitude or coding tests.
Tips: Time given was enough for other sections but you need to hurry a little in aptitude part.
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
Skills: willingness, Enthusiasm, Coding skills, Aptitude skills

I appeared for an interview before Apr 2024, where I was asked the following questions.
- Q1. What are the basics of the refrigeration cycle?
- Ans.
The refrigeration cycle is a thermodynamic process that removes heat from a designated area to lower its temperature.
1. Evaporation: Refrigerant absorbs heat from the environment, turning from liquid to gas.
2. Compression: The gas is compressed, increasing its pressure and temperature.
3. Condensation: The hot gas releases heat to the surroundings, condensing back into a liquid.
4. Expansion: The liquid refrigerant expan...
- Q2. What is the difference between chillers and Variable Refrigerant Flow (VRF) systems? What are the different types of compressors?
- Ans.
Chillers and VRF systems differ in design, application, and efficiency, with various compressor types influencing performance.
Chillers are centralized cooling systems, while VRF systems are decentralized and allow for individual zone control.
Chillers typically use water or refrigerant to cool large buildings, e.g., centrifugal chillers for commercial use.
VRF systems use refrigerant as the cooling medium and can simulta...
- Q3. What is COP and heat load calculations. Types of PCBs in VRF. What is AHU and types
- Ans.
COP measures efficiency in heating/cooling systems; heat load calculations determine required capacity for HVAC systems.
COP (Coefficient of Performance) is the ratio of useful heating or cooling provided to the energy consumed.
Heat load calculations assess the thermal energy needed to maintain desired indoor temperatures.
Types of PCBs (Printed Circuit Boards) in VRF (Variable Refrigerant Flow) systems include control P...
