There are a lot of reviews for technical phone and HR interviews. So I am focusing on Onsite interview Questions. JAVA Given few code snippets and asked to find errors. A program which tried to remove star along with character preceding and succeeding it. Something like String s = “abcsd*sdfsdf*asd”; String t = “” for(int I =0; i< s.length(); i++){ String temp = s.charAt(i); if(temp == ‘*’){ //Some erroneous code trying to blank out character at i-1 and i+1 //and making t = s } } System.out.println(t); A Code on Multi threading Class MyThread extends Thread{ int myNum; static int count; Mythread(int i){ super(); count++; myNum = i; } public void run(){ System.out.println(“Count is”+count +”MyNum is”+myNum); } Public static void main(String args[]){ for(int i =0; i <4; i++){ MyThread mt = new MyThread(i); mt.start(); } } } Code Garbage collection Which of these objects are eligible for garbage collection class Test{ Test obj; } class Main{ public static void main(String args[]){ Test t1 = new Test(); Test t2 = new Test(); Test t3 = new Test(); t1.obj = t2; t2.obj = t3; t3.obj = t1; t1= null; t2 = null; t3 = null; } } C/C++ Shown code to find errors or outputs char c[] = {'a','b','c','d','e','f'}; char d[6]; while(*d++ = *c++); class Test{ public: static int count; Test(){ count++; } } Test::count = 0; Test t1; Test t2; Test t3; cout << t1.count << t2.count << t3.count << endl; Given a function int myfunc(B* obj){ //Does something } Asked which of the following calls are valid given the following hierarchy A / \ B C / D B* b = new B; D* d = new D; A* a = new A; C* c = new C; myfunc(b) myfunc(d) myfunc(c) myfunc(a) Math Was shown a function on the board and asked to draw its derivative Was given a parabola y = 12 - x^2 (symmetric about Y axis) and asked to find the max area of a rectangle that rests on X-axis and is inside the parabola Programming Concepts Asked to write program to draw 1/8th of a cirlce Asked to write a sorting program Shortest route for an ant crawling on a solid cube from one corner to diagonally opposite corner Signal Processing Given two discrete sequences and asked to find convolution Asked difference between Discrete and Circular convolution Given a sequence x[n] and asked to find step interpolated down sampling x[2n - 0.5] and up sampling x[n/2 + 0.5] Manager Interview/ HR Interview What would your manager say about you? Both positive and negative. Any other offers?
