  • Q1. How Vacuum column work?
  • Ans. 

    Vacuum column is used in distillation process to separate different components based on their boiling points.

    • Vacuum column operates under reduced pressure to lower the boiling points of the components being separated.

    • The column is packed with trays or structured packing to increase the surface area for vapor-liquid contact.

    • The feed enters at the bottom of the column and is heated to its boiling point.

    • The vapor rises up...

  • Q2. What is Octane number?
  • Ans. 

    Octane number is a measure of a fuel's ability to resist knocking or detonation.

    • Octane number is the percentage of iso-octane in a mixture of iso-octane and n-heptane that has the same knocking characteristics as the fuel being tested.

    • Higher octane number means the fuel has better resistance to knocking.

    • Octane number is important for high-performance engines that require high compression ratios.

Interview Preparation Tips

Interview preparation tips for other job seekers - This interview was a technical one but was majorly a stress test. It lasted for about 1 hour . The interviewer wanted to test both my knowledge and communication skills. Most of the questions asked to me were related to my B.Tech curriculum i.e. Fire & Safety related topics. He stressed a lot on the basics related to my project topic. Luckily I was able to answer most of the questions correctly. I tried to answer each question with examples and also used props on the table (like pens, paperweights, pen stands etc.) to explain my theories. It was my first offcampus interview, and I think I did pretty well for a fresher. You need to stay calm and should apply presence of mind.

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.

Interview Preparation Tips

Round: Test
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.

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).

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.

All the technical questions were theoretical questions and no problem solving.
Tips: Briefly touch up all the core mechanical subjects and you will be through the test.
Duration: 1 hour

Round: Technical + HR Interview
Experience: Firstly, a form was given before the interview. In the form, they asked us to fill all our bio data, projects we have done and some basic HR questions. There's only one interviewer. The first question was "Tell me about yourself". He asked based on what we have written in the form. He asked about my goals, role model and also about the company. He mostly checked whether I am interested in the company or not.
Feedback from others - Projects, Interns and technical questions on material science.
