Onsite - 1. You have a computer with seven core cpu, you have a file and you have to read each line of the file, check if it has the word UPS in it, if so , then write it to a file, if there is no word as UPS in it, write that line to a different file. 2. An amount will be given as input. The amount will have some cents in change. So, for example $29.90. For the change, you have to start using the highest denomination and go to the lowest until the change value is completely met.
The FedEx director asked ,"would you have a problem working with someone that is younger or less experience than yourself ?"
What would the count for the list of it. public class Test { string Data; int Id; public Test(int id, string data) { Data = data; Id = id; } } static void Main(string[] args) { List<Test> list = new List<Test>(); list.Add(new Test(10, "test")); var d = new Test(10, "test"); if (!list.Contains(d)) list.Add(d); Console.WriteLine("Count of the list is : " + list.Count); Console.ReadLine(); } } What to do to make count 1?
• Basic math What is a derivative? What is an integral? What is the relationship between integral and derivative? What is an eigenvalues? What is an eigenvector? Having this matrix: A= [[2 1];[-1 2]], what are the eigenvalues? what are the eigenvectors? How did you calculate these? What is a linear differential equation? Why? Explain? What is a singular matrix?? What is a symmetric matrix? What is an identity matrix? Having A=[ 2a 3g 4k] and B=[3a 2g -1k], what is the dot product? How did you do it? Factorize your answer. If A and B are matrices, what properties should these have to can be multiplied? • Programming concepts What is a virtual statement? What is a break statement? What is the difference between break/continue statements? What is a destructor do? What it is important? If you have a virtual statement, do you need to assign your destructor as a virtual? Why? What is a recursive function? Give an example. • One programming language (C++) What this line of code does? # define alpha beta What this line of code does? # define alpha 100 What these lines of code do? # if def alpha # end if what is the difference between malloc and calloc? • MATLAB How you save a variable in a mat file? How you save some specific variables in a mat file? How you open these data? How can you see the type of a variable? How can you do the inverse of a matrix? How you do the transpose of a matrix? What A.*B does? What A*B does? What A.’ does? What A.^-1 does? What A’ does? How you find help in MATLAB? How you plot a variable? What is a script? What is a function? Is a script the same that a function? If you type A=1 the answer is A=1 if you type 1 the answer is ans=1 How you do to don’t see the answer?? Using ; • Signals Processing What is z transform? What's the expression? What is the region of convergence? If you have a pole in the unit circle (exactly in 1), is the system stable? If you have a pole outside the unit circle, is the system stable? What is a causal system? What is a linear time invariant (LTI) system? Why? Explain? How it works? What is a LVR system? Why? Explain? How it works? If h[n]=[ 1 2 3 0 1], where the value of 0 is in n=3, what is the Z transform? If x[n]=n and y[n]=delta[n-3], what is x multiplied by y What's the difference between Continuous-time and Discrete-time systems? Can you convert a continuous system in a discrete system? How?

What is the minimum sampling rate required to digitize the following signal such that the signal can be recovered without aliasing: 3cos600πt.
very quick. yet to finish it. currently in the 3rd round. first round was a prerecorded HR round with 5 questions. Second round was coding with hackerrank containing math, to choose any 2 of the 5 languages.
