Was referred by a friend and got an email in two weeks for a HR video interview. It consisted of basic HR questions (already listed on Glassdoor). After this round, I got another email to take part in a Technical interview which was over the phone. I had given my best for this day and answered about 90% of the questions. Here I want to share my technical interview questions, I remember most of the questions. Hope it helps many of you and All the very best! Maths: 1> What are Eigen values and Eigen vectors. I was given a 2*2 matrix and told to calculate the values 2> Definite and indefinite integrals 3> Invertible matrices. They gave me a 2*2 matrix and told to see if it was invertible 4> Given velocity v=2+3*t^2, calculate acceleration after 3 seconds and position after 4 seconds 4> f(5)=3, f'(5)=8, calculate f(3) if f''=0 in all domains (I didn't quite understand this question) 5> They gave me a simple ODE and told to solve it. 6> Define order and degree of a Differential equation 7> What is rank of a matrix. Given a 2*2 matrix, find its rank 8> Given a Differential equation, find its degree and order -------------------------------------------------------------------------------------- Java: 1> What is the difference between int and integer 2> What makes a JAVA program run faster 3> Define packages in JAVA 4> Pointers (Though JAVA doesn't have pointers, they asked me for its definitions) 5> What is the significance of 'Finally' Keyword 6> What are recursive functions 7> Significance of EXIT command in recursive functions. 8> Garbage collectors 9> Does JAVA call by value or reference 10> JRE and JDK 11> What are generics in JAVA 12> What are primitive data types in JAVA 13> What are abstract classes and interfaces in JAVA 14> What is inheritance 15> What is polymorphism and define over loading an over riding in it 16> What makes JAVA a OOP 17> Difference between & and && --------------------------------------------------------------------------------------------- Control Theory: 1> Why is a open loop feedback used for a stepper motor? 2> Why is negative feedback preferred. ? 3> What is controllability ? 4> What is a Bode plot? 5> Given a 2nd order equation y''+4y'+20y=0; find the poles 6> What is PID controller and signify all aspects 7> Effects of poles on rise time 8> Lyaponov stability criteria 9> Given a equation of the system, find its damping ratio and natural frequency 10> Effects of poles on the stability of a system ----------------------------------------------------------------------------------------------- MatLAB: 1> Significance of these symbols %, ~, ..., !, @ 2> Difference between A^2 and A .^2 3> How do you save a file using codes 4> How do you modify axis labels 5> How to clear work space
