(5 Questions)
- Q1. What is stress and strain and how can we measure these quantities?
- Ans.
Stress and strain are measures of the internal forces within a material. Stress is the force applied per unit area, while strain is the deformation of the material.
Stress is the force applied per unit area on a material, measured in units like Pascals or pounds per square inch.
Strain is the deformation or change in shape of a material due to stress, measured as a ratio of the change in length to the original length.
Str...
- Q2. What is Fatigue failure?
- Ans.
Fatigue failure is the weakening and eventual breaking of a material under repeated or fluctuating stress.
Occurs due to repeated or fluctuating stress on a material
Can lead to cracks, fractures, or complete failure
Common in metal structures like bridges, aircraft, and machinery
- Q3. There are two type of loads present on the basis of variation of 3 load parameters, which are force magnitude, direction and point of application. If all these parameter don't change with time, then it wil...
- Ans.
Static loads do not change with time, while dynamic loads involve at least one changing parameter. Fatigue failure occurs when a body is subjected to continuous dynamic loading.
Static loads have constant force magnitude, direction, and point of application
Dynamic loads involve changes in at least one of the load parameters over time
Fatigue failure occurs when a body is subjected to continuous dynamic loading, leading t...
- Q4. What is NPSH of pump?
- Ans.
NPSH of a pump stands for Net Positive Suction Head, which is a measure of the pressure available at the suction port of the pump.
NPSH is important for determining if a pump will operate properly without cavitation.
It is calculated by subtracting the vapor pressure of the fluid from the total suction head of the pump.
NPSH is typically provided by the pump manufacturer and must be greater than the required NPSH for the
- Q5. NPSH stands for Net positive suction head, which signifies pressure by the fluid on suction side of centrifugal pump. It must be greater than the atmospheric pressure because it this not happen then cavita...

Interview Preparation Tips
Experience: Aptitude:
Time was short. 3O Qs in 30 minutes was a time-crunch. As my aptitude is weak, I had put in prior efforts to put up a decent performance. I could solve around 14-15 Qs in that time.
Technical:
50 Qs in 30 minutes. The Qs were fairly on easier side. Just that, Qs spanned all across chemical engineering, with almost equal weightage on all topics. Most Qs were from past years' GATE papers. I attempted around 40 Qs.
Tips: 1. For aptitude, prepare well in advance if you are weak.
2. Strengthen technical by solving MCQs from Indiabix.com
3. Since there are no negatives, go for most Qs.
Duration: 60 minutes
Total Questions: 80
Round: Technical Interview
Experience: I had a good technical interview. Most of the Qs were logical. The interviewer made sure I was comfortable through out the interview, each Qs was followed by a light Q.
Tips: 1. Be cool as a cucumber. 2. Be thorough with all subjects.3. If you think you don't know answer, think logically.4. Try to deviate the Qs to your strengths.
Round: HR Interview
Experience: It was the most relieving interview ever! It was very jovial and open-hearted interview.

- Q1. Tell me about yourself?
- Q2. Why do u want to join RIL?
- Q3. Why the gibbs free energy is called free energy?
- Ans.
Gibbs free energy is called free energy because it is the energy available to do work at constant temperature and pressure.
Gibbs free energy is the maximum amount of work that can be obtained from a system at constant temperature and pressure.
It takes into account both the enthalpy and entropy of a system.
If the Gibbs free energy is negative, the reaction is spontaneous and can do work.
Examples include the combustion o...

Interview Preparation Tips
Experience: Overall it is a balanced paperIn aptitude, No of questions is 30 in 30 min. most of the question were easy and mostly they are from topics like work, speed, time, distance, series. Some questions are from English like word meaning, antonym, synonym etc.In technical, no. of questions is 50 in 30 min. The questions were from whole of the chemical engg like from thermo, mass, heat, cre but not from process control or instrumentation or from chemical technology. Most of the questions were conceptual and are just theoretical.
Tips: For apti, try to solve questions from www.indiabix.comFor technical, brush up ur conceptual knowledge and try to learn more and more of mass, heat, themo and cre.
Duration: 60 minutes
Total Questions: 80
Round: Technical Interview
Experience: Overall my interview experience is good. I gave around 70 percent of the answers. My interview is purely technical but it was not so with my friend. His interview is 90% HR.So u never know what type of interview u r going to face when u walk in there.In my interview the questions were mostly asked from thermodynamics and its applications.
Tips: Be calm and confident.Try not to get nervous.Never try to attempt the questions of which u don't know the answers. Attempting those questions and thereafter not giving answers properly gives a bad impression.
General Tips: As I previously told try to remain calm and not get nervous.If u do so no one can take that job from u.And by chance u don't get selected, then do not get disheartened and just think about ur mistakes and try to improve them as U are the best judge of yourself.
Skill Tips: Do not get nervous in the interview.Do not try to solve the whole technical paper rather go through it and attempt the questions u think u can do.For improving communication skill, try to communicate with ur friends in English. Read newspaper and communicate with urself in mirror ( this method will particularly help u a lot in improving ur communication skills and will also free u from any kind of presentation fears).
Skills: Confidence, Time Management, Communication
College Name: MNIT
Motivation: yeah RIL is a very good company, very large and with a lot of scope.So just go for it as if u want to build ur repo then it is one of the best platform to do so.
Funny Moments: one of my friend got injured before the interview. So when he entered for the interview,HR saw his hand and asked what happened. So he hold HR that he got slipped on stairs. After that HR said to him "khudko ko sambhal nhi pa rhe company ko kya sambhaloge".. So try not to lose ur senses if u face such kind of things .They just purposely do that to check how u can perform under pressure.And that friend of mine was also selected for the job.
