Defence Research & Development Organisation Graduate Trainee Interview Questions and Answers for Experienced

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.

Duration: 60 min minutes

Round: Interview
Tips: Prepare Design subjects properly. Try to Know the Physical significance of every possible topic.
Keep Calm and if you a little bit answer try to frame it..interviewer will help u if u r on right track.
But don't stick to a question if u have no idea about that..

Round: Interview
Tips: If you are mentioning your strengths and weakness then be ready with at least one example.
Focus on your strength
Think and answer
Try to give real answer

General Tips: If you are in Mechanical System Design. You have a high chance. Prepare all design subjects.
Skills: Technical Knowledge
College Name: IIT KHARAGPUR
Motivation: Dream company for people who want to work in core engineering.
Edison Engineering Development programme is world recognized

Round: Test
Experience: The test conducted had three parts (each part is approximately one hour long).
Part-1: Tested mathematical and analytical skills. The questions were quite simple and one hour is more than necessary for this part. 
Part-2: Tested technical skills. The questions in this part are administered depending on your department (AE, ME, EE). Each of the three eligible department gets the appropriate technical test. I can only attest to the aerospace test. The aerospace test was mainly about fluid mechanics and jet propulsion. The questions can be easily answered if you have a good grasp of your third year syllabus on jet propulsion. 
Part-3: It was related to HR. They asked about why I thought GE was special, why I think I am special, what my career goals were, etc.
Tips: DOs: Be relaxed and answer the test attentively. GE places enormous importance on your technical knowledge. Therefore, do ensure that you prepare for the test by brushing up on your third-year jet propulsion course. 
DONTs: There will be enough time to complete the test, don’t rush.

Round: Technical Interview
Experience: Technical interview may in itself consist of two rounds (like I had). The three eligible departments are further divided based on your field of interest. In aerospace, there were three sub divisions: dynamics, structures, and aerodynamics. Each sub division has an expert panel to interview you. I went to the dynamics panel (two rounds). In the first round, they asked me fundamental questions about dynamics in aerospace engineering: vibration of a beam, natural frequencies, mode shapes, etc. Some questions on fundamentals of jet propulsion: Brayton cycle, parts of jet engine, etc. In the second round, they asked me questions more directly related to GE’s core interests: jet engines. Rotordynamics is an important aspect of jet engine R&D. They asked me about the various modes of a jet engine rotor: bouncing, pitching, bending, etc. They asked me about the critical speeds at which each of these modes would get excited.
Tips: DOs: The usual: be confident, relaxed, speak slowly and clearly. Be friendly.

Round: HR Interview
Experience: The HR wants to know why you want to join GE. Don’t give cliched answers like GE is a big company, GE is great, etc. They already know that. They want to know why you feel GE is the right place for you. On the other hand, they also want to know why GE should take the trouble to hire you. Be confident and speak about your strengths and weaknesses, but don’t make it seem as though you are gloating. Having good communication skills will always help you in this round.
Tips: DOs: Speak freely, act like you are having a conversation and not a rigid interview. GE is a liberal company and they like people who are naturally confident and can speak comfortably. Smile. 
DONTs: Make it seem like your answers are rehearsed.

General Tips: GE needs to be convinced that you will not go on for higher studies. You have to convince them that you will work for them for a long period of time.
Strong technical basics, good academic profile, good and relevant projects are basic requirements. Publications are an added bonus. GE goes the extra length to make sure that they don’t hire students who will end up going abroad for higher studies. They literally grill you about your higher educational goals versus your professional goals and seek to know which is more important to you. All the best!
Skill Tips: Math ability is quite important but quantitative ability as required in CAT is not really necessary.
Programming: MATLAB, C, C++
Software: Simulink, ANSYS, FLUENT
College Name: IIT KHARAGPUR
