1,952 applications support engineer interview questions shared by candidates

Some of the questions were: Control Systems: - How's an LTI system stable? - What are Eigenvalues - Find stability of LTI system - Find Eigenvalues - Phase Margin? - State Space formulation - Observability, Controlability - Rank of a matrix - Control canonical form - Lyapunov stability - Find poles of a system - What is Bode plot? Math/Algebra: - Solve an ODE - Diff b/w ODE and PDE - Solve a limit involving indefinite terms (used L'ospital rule) Programming, C: - malloc - const - Recursive function. Give example - Difference between passing a pointer and a variable to a function? - Null pointer? - Sturctures? - Diff b/w structure and unions? - ptr ++ - Some simple for loop questions Programming, MATLAB: - Defining path of folders - Clearing and importing variables - Making an array of numbers divisible by 3 - Concatenating strings That's pretty much it. In total there were 32 questions. I got 27 of them right, and the remaining I either didn't answer or gave him the general idea since I could not recall it at the spur of the moment. From the other reviews, it seems there is not a lot of hope but; let's see. Fingers crossed. Hope this helps.
