Tips: Don't try to be over smart.

College Name: NIT SURAT

Round: Test
Experience: Not mentioned before but later in the offer letter i found that CGPA must be more than 7.5. It was a technical test. Heat transfer, thermodynamics, stress, material strength, fluid mechanics were all asked. Time management and accuracy is essential.
Tips: Questions are not hard (average) but time is very less . So one must be quick and accurate. Don’t waste time on a single question if you are stuck.

Round: Technical Interview
Experience: Technical interview for short listed students based on their field (thermal or structures). I am from thermal background. All my questions were based on heat transfer and my project. Some of my friends were asked questions on fluid mechanics, turbo machinery. The questions which were asked to me were: 1. They gave me a plate and asked to discuss the heat transfer through it . Later they asked me about how to find the heat transfer coefficient (I answered: Nu=h*l/K). Then they asked me the significance of Nu. After this they asked me about Re, Pr numbers (some other numbers in fluid mechanics). They asked about Bi number, significance of Bi number , lumped body assumption and when this assumption can be taken. They also asked me to prove that. They asked me about CFD modelling, Finite Element Analysis as my projects were based on that. They are very particular about physical significance of terms and majority of my questions were on that.
Tips: Do not mug up concepts as they ask every question in detail. Your answer to the first question leads them to their next question. Even if you do not know the answer, try to work out from basic concepts. You might even get help from the interviewer if your approach is good. If you are completely unaware of the question, tell them frankly about that and they might ask you other question where you might be able to impress them rather than wasting time with something you don’t know the answer to.

Round: HR Interview
Experience: General HR questions for short listed candidates (Technical is a bit difficult, once you clear that be confident; HR is very simple)
Tips: Be confident and maintain eye contact. In the middle of the HR interview, he might ask you suddenly about your academic project. So, stay conscious.

Skill Tips: People with knowledge or experience in CFD modelling have an edge(especially for thermal and aerospace). People who are very good at stress analysis, strength and structures are preferred ( for Manufacturing specialization and aerospace)
Academic credentials (My CGPA 8.18) was not that great but i answered all the questions in the interview) are very important . All the questions are related to the basic concepts but student must be well aware of them.
Be thorough with the basics of Thermodynamics, heat transfer , fluid mechanics (for thermal and aerospace students) stress analysis, material strengths , design of machine elements (for manufacturing specialization). Don’t mug up the formulae , know about their physical significance. Most of the questions will be on basics, don’t waste ur time mugging big equations and derivations. The GATE book saved me a lot of my time. I went through it to get a basic idea of all the concepts and for each concept present there, I browsed the internet to get a further insight.
College Name: IIT KHARAGPUR

Round: Test
Experience: CGPA of 8 is the minimum criteria.
10 aptitude questions: 15 minutes, no negative marking, level: medium/easy 
10 technical questions: 15 minutes, no negative marking, level: easy/medium (there were 2 sets: 1. structures; 2. aero/thermal; we had to choose one as per our interest) Basics should be clear, no formula was required to solve the technical paper.
Tips: Solve the technical paper related to your project field irrespective of the toughness of the paper.
